Would a 4 speed bolt up in the same spot without modifications? Does the 4 speed for the same truck have the same gear ratios, other than missing 5th?

Hmmmmmmmm.......................

Thanks. Let me explore another avenue. If everything inside is too crunchy, how hard is it (with a clean space and normal hand tools) to take this thing apart and replace the shaft bearings? That seems like it would be relatively cheap, parts wise, but would... uh... stretch my skill set. Then I'd just live with whatever gear slop there was, knowing the thing isn't just going to go BANG on me. How big of bearing press would I need?

Also, I'm in a climate with road salt. There aren't a lot of old ones around. What's the latest thing that works?

(stupid question)

So my transmission is noisy, and it turns out there was quite a bit of metal flake in the lube. I'm not sure this transmission is going to live. This is (as I said) a 720 with an L20b, which means it's a 1980 model year. What years of trucks and motors will have compatible transmissions? I understand the Z24 leans over, but the tranny mates up? What are my options?

I'm thinking. The seller said the Weber might need to be re-jetted. And it needs a bunch of other adjustment. And a lot of cleaning. If I just want the thing to run right, does it make sense to just pay the $250 and get a new carb, rather than fuddling with the old one?

I've found some spare 15" rims. I'm thinking 205/75r15 snow tires.

I'm working with the Haynes Manual (yeah, well, it's what I have for now) and on page 7A-3, illustration 3.5a shows how on earlier models there's a pin that holds the shifter. This pin is a pivot for pushing the control forks back and forth. On my 521, it came loose, and once I replaced it, it tightened up the system considerably. This is for early models of the 720 as well. Mine was built during the Carter Administration, so.... I can hear it rattle. Regarding the carb, I'll have to look at all those things. I'll start with basic carb cleaner and go from there.

My first was a 521 I had 15 years ago. I brought my second one home today: It's a 1980 720. It's got the L20B, manual steering, and the AC compressor is no longer installed. No great loss. I'm going to have to patch the rocker behind the driver's door, give it new brake pads, tighten the shift linkage bolt, and get rid of the mice in the vent system first. It's got a weber carb that the previous owner said ran a bit rich. My chief advisor tells me that the first thing to do is get a fuel pressure regulator to take it down to 1.5 psi, which is Weber spec. Then a bit of cleaning and tuning and the carb should be okay. The seats may have come out of a Camry. The previous owner wasn't sure. All I know is that they don't fold forward enough to get behind them, and I won't have passengers very often. I may just pull the passenger seat so I can carry my equipment. My other truck is an '86 Toyota 1-ton. But this Datsun is going to be my winter truck. Badges? We don't need no stinkin' batches! It still needs a name.

New guy here. I'm looking to get my second Datsun: a 720. My first was a 521, 18-15 years ago. What I'm driving now is an '86 Toyota Pickup, 2.4L, 1 3/4" pipe. In the last year, I've replaced the muffler and the cat, but not at the same time. If I had it to do again, I'd do both at once and use 2" pipe, for the simple reason that 1 3/4" pipe and exhaust parts are getting to be an odd size out there. I couldn't find a slip-fit universal cat, and had to use a 2" and make my own half-assed adapters. I'm not a speed and power freak. I'm not a fanatic about everything being original. I want a truck that gets me from here to there and hauls stuff efficiently. And when it breaks, I want to be able to fix it with the least fuss. That's why I'd go 2" all the way.

Maybe. But I'm hoping that whoever got him really did restore him, and I'll see him here.

I had a 521. I gave it to a neighbor south of Tacoma WA in 2000, and around 2002 they said some kid came and begged them to sell it to him, because he was going to fix it up. It was a '71. it was rattlecan orange. I'd had some electrical issues, and I had reflective tape around the bed. I found a '69 (I think) on the roadside once and stole the all-metal dash out of it and put it in my truck. The mechanics I brought it to said the front spindles were out of a 620. He had a sunroof. His name was Gort. He came in pieces. I'm just hoping he's out there, doing well.
