Sorry for the late reply and update to the thread. Work has been taking up all my time recently! Here is an album of a few pics of the axles. For space in the page sake I am just going to leave them in the link and not post them directly here. http://imgur.com/a/WwZkJ I should have the brakes done tonight after work I am hoping! I got it all installed last week and was having problems getting brake pressure so I disconnected the hard lines from the 3 flex lines (two in the front and the one to the rear) and made sure I got fluid to all of that and I did. I sprayed some carb cleaner in the flex lines and put some compressed air through them and some real nasty gunk and crap came out. I am assuming the lines need to be replaced so I am going to buy all of that from Rock Auto. For now though I am just going to roll with it. I am going to bleed the brakes tonight hopefully and then hopefully the thing will have brakes. I got the throttle figured out. Turns out the carb came out of a 510 wagon which used a throttle linkage. I engineered a throttle cable bracket and a lever arm that bolted the the fork on the carb. It looks way rigged together but I am trying to get this thing on the road without spending much :P I am deciding if I want to just eat the money and get a weber 32/36 or decide to do something else engine wise. Kinda want to stick a KA24 in it but not sure how nice that will play with the 4x4 dealio so might just stick with the L20B. When frustrated with the brakes or when without a helper I have been tearing apart the interior and deep cleaning the truck. Its had one other owner and been on a farm all of its life so its pretty gross. I have been using a rust removing pad on a drill and been buffing the floorboard under the seat back to bare metal to be recoated as it has some surface rust. I am trying to figure out what to do with the foot wells as they both have wholes in them. I also have been decluttering the outside. I drilled out the rivets in the fake hood scoop. Took off that hideous rear bumper. I also took off the headlight shade things and have been working my way towards the cab lights. All in all it is really coming along. After I get it in good mechanical order I am going to strip the outside and start prepping it to be painted!

Looks like a refurbished master cylinder is $30 at oreillys with a core. I'll just do that. How should I clean the lines out? Also would this explain why there is no pressure in the pedal?

Not a bad idea. Do I need to secure the throttle cable down anywhere? Right now it comes out the firewall and just flops around. What's the spring and washer do? Have any pics?

I bought a single owner 620 this past weekend but the throttle wasn't hooked up and the brakes weren't installed (see my thread in the brakes section of the technical forum). So the throttle cable is there and connected to the pedal and through the firewall but this is what the throttle body(?) end looks like on the carb. It rotates clockwise (if looking at it towards the front of the truck) when at wide open throttle. I do not see any markings on the carb to indicate what it is, I know it's not stock as I have the stock one sitting in the passenger seat in a milk crate. Here's some pics of the throttle body(?): Any help is appreciated.

So I bought a one owner dealer converted 4x4 620 this last weekend but it had no brakes. Runs like a champ without hesitation, but its got no brakes. Luckily for me however I was given a box of brand new parts for the front and the rear drum brakes. The fronts went on without a hitch. The rears however could go burn in hell for the rest of eternity. So essentially the rear brakes are stunting me because of the parking brake. The parking brake lever cannot rotate counterclockwise enough into the space of the shoe so that the fork or the parking brake strut or whatever makes complete contact in all the slots. Right now it leaves a bit of a gap in one of the slots on the side with the parking brake lever. Because of this is spaces out the brake shoes and so when put together the shoes do not make full contact with the slots in the piston and the adjuster on the top and bottom of the assembly because they simply cannot come close enough because of the parking brake assembly. I disconnected the parking brake line so I know that the parking brake isn't engaged. What am I doing wrong? I have the adjuster all the way in by the way, at its lowest point. I have the other side of the car for reference as that brake was already installed and it sits totally fine, that being said the adjuster is out quite a ways. My last little issue is there is absolutely no pressure in the brake pedal. There is fluid in both reservoirs on the master cylinder but there is like dirt at the bottom of the reservoirs, like 1-3mm of just black goop at the bottom so I am thinking just air in the lines or something? Not sure, going to take off the reservoirs and clean them out and hope for the best. Any help is so greatly appreciated this is already driving me absolutely nuts.

I will get those photos. Axle in the front looks solid though. Are there any full write ups on replacing the front and rear drum brakes? I can't find anything and I am having one hell of a time with this. All I can find is on disc conversions. Also any write ups on connecting everything up to the carb? The throttle isn't currently connected.

Small update on the truck (more to come tomorrow as it is still sitting in the trailer and am in my house in my college town and not in my parents home where I am staying for the summer.) So I bought the truck for $800. The car was bought by a Richard and Kathleen E for $6,100 on June 21st 1977 in Great Falls Montana with a monstrous 8 miles on it. It then made the trip to Bozeman Montana where it stayed in their possession for 40 years. The engine was rebuilt at 92,841 miles by (the name of the shop and all receipts are in the car I would have to check the name. Today it has 148,xxx on it with a notebook sitting in the glove box of every single oil change ever performed on it. Original documentation as well as the dealer information is also in the truck (seriously more detailed than I have explained here, I still have more to go through). Anything you could want to know is in there. I am now the second owner of this truck (the original title is in the truck). It fires up without a second guess and it was driven into the trailer (throttle isn't connected so the idle was raised and the clutch let out.) and stopped by killing the engine (no brakes, sitting in a milk crate in the passenger side.) The truck came with 3 sets of tires, 3 sets of rims and a spare. (not sure if there is a spare under the bed?) The truck also has a new clutch and some other new parts. The lights work, all the gauges work (except the fuel gauge [Will need help with this]). It also is going to need most of the rubber pieces around the truck (rubber doesn't last 41 years :rofl: ) After we drove the truck into the trailer and I counted out eight big ones to the young guy that was selling it to me then asked if I wanted to see his 280z, (we had been talking about my Evo 8 previously). We walk over to a "garage" on a dirt driveway built out of tarps draped over metal bars. Inside is a blue old 280z and a small tool box. And in the 280z? An Vortec LS with a 66mm turbo strapped to it. Easily one of the craziest things I have ever seen, built in a tarp garage with no more than a little tool box on a dirt driveway. As I stated above, I own a 2003 Mitsubishi Evo 8 that has been proffessionally painted and is making about 400 at the wheels. A decent car that is about as immaculate as it goes but today, this little $800 datsun is easily the coolest way I have spent $800. To learn the history of the car and the people who owned it, to be the second owner of a car that averaged 3,700 miles a year, has been amazing. Its been a crazy day. Tomorrow morning me and the girlfriend are packing up and heading back to Billings where I plan to get the brakes installed and the throttle hooked up and get the thing driving tomorrow. I would love all of you to ask any questions you have. This is the first car I have ever owned that was built before 2003 so I don't know much about old cars or what information people know about them but this is easily the most complete car I have seen. There is so much information here I am just absolutely speechless although I am probably over reacting.

Will definitely get those pictures on Saturday when I pick the truck up. The brakes aren't installed to my knowledge. He's got all brand new parts for the front and rear drum brakes but did not install them. He also hasn't got a throttle installed. That's why the truck doesn't drive. It starts, but it doesn't drive.

Ehh I'll learn to love it. It's different and its rare. It's got 148,000 on the body and 48,000 with receipts on the motor. Only one dent in the car in the front passenger fender. Pretty clean little truck, and all for $800 with two other sets of tires and the original wheels? Heck yeah.

Starting to sound like I will be learning to love the lifted 4x4 life haha! Thats perfectly okay with me. Would rather not destroy something rare like this. That means I shall go into full resto mode! I want to fix the body, (the one dent in it) and remove any rust (only one real rust hole in it is under the driver footwell) and then coat the underside to prevent it in the further! Also want to make the interior nice and new! Any other recommendations? The truck does start but does not drive, the throttle is not connected and brakes are not installed I guess. I am picking it up on Saturday so I will update you all more then!

I'm definitely going to have some fun with it for a while! Who knows, maybe I'll fall in love with the lifted 4x4 world and keep it that way, lord knows me evo is low enough :P Figured I would ask to see if it was even possible to lower however.

Yeah the pics of the interior show the selector down on the ground. It looks rather OEM like it's been there since the car was there ya know? As far as why I want to lower it. I just really like the look of lowered 620's. If this car was one of the converted since day 1 sort of models would the leaf spring be under the axel just like on regular 2wd 620's so to lower it I could just get some lowering blocks or how would I go about it?

Is it just too much work to try to lower that it makes it not worth it or how does that go? I plan to enjoy it for how it is right now but I do really like lowered cars haha.

So my name is Nate, I am a mechanical engineering major in Montana. Previous to this upcoming weekend I have owned a 2006 Hyundai Tiburon and then my current car my 2003 Mitsubishi Evo 8 and my daily which is a 2007 Subaru Legacy. Needless to say I have never owned anything old nor have I ever owned a truck. So I have loved these things since I was little, minitrucks have always fascinated me. Fast forward to today where I closed the deal to go pick up a 1976 Datsun 620 about 350 miles away (will be trailering). So after agreeing to a price of $800 I have been doing some research. First off it was lifted, something that I kinda want to reverse, kinda looking to go the lower route. It's also a 4-wheel drive, which to my understanding wasn't available in the 620? So what am I buying here? It looks like a 620 but apparently only the 720 had a 4-wheel drive option? And how would I go about reversing the lift? Thanks for the help guys!
