521Symmonds

Thanks for the advice and a bit of direction. I'm assuming bebanni's custom upper arms would afford that adjustment Wayno was talking about. I'm in that "I wonder if I can make this work in a not extremely painful and complicated way" stage and I know everyone here has the knowledge and experience to save me from going down some dead end streets. Also, that's a sexy truck there Charlie!

So, while I was wandering around junkyard I happened to find a guy trying to pull an engine out of a 85 pickup. Helped him out, and he gave me the whole front end out of it for free. I was wondering if the RWD set up mostly bolts into a 521. I'm unsure if the torsion bars had a matching spline design(trying to keep the original bars installed),and I'm trying to avoid tearing down the front end of my truck to find out. It would be nice to have ball joints and front disk brakes though.

https://goo.gl/photos/q2x2XBykTUbknLrk7 I was just under my truck(2011 Frontier) and noticed that the rubber part looks pretty similar to the one out of my 521. I'll have to give that a try seeing that most of the rubber in my 521 is gone.

Thanks for the heads up, I was hoping that they had matching kingpin sizes to just do a quick swap. Unfortunately I live in boston now and 521's have been hard to come by.

Is a 620 drum brake spindle interchangeable into a 521? I'm having zero luck finding a replacement so far. I can probably get the origional re machined but I'd save that as my last option.

An oldie but goodie of my 521 and my frontier

Well this thread explains why I can lock up my rear brakes on command on my 521. I got 620 rear brake cylinders. I'm going to revive this thread with a question. My 521 rear right side brake is sticking to halfway whenever I drive forward. I will get a grinding sound like my brake shoes are barely touching the drums and I get a soft brake petal. So far I had flushed the brakes, checked all of the lines and found no leaks, checked the cylinders with no leaks, and bled the system with no issues. I go in reverse and it stops with no issues, it just happens going forward. Does it sound like a bad rear cylinder?

Yeah I'm going to get that battery checked out soon. Popped the fuse box back in, replaced a few connections and a lot of contact cleaner and it runs again with no issues. This datsun just needs a lot of bandaids til its not my daily driver. The fun will begin after that.

Flat: I'd love to rewire my truck, but I got to drive it to work tomorrow :blink: Dan: terminals are clean, battery is on a charger atm due to leaving the key on on accident. Thankfully when I turn the key off, battery goes to 12 volts by itself, but I'm topping off for security. I'm not sure the alternator is thinking its charged when I can't get the damn thing to turn over because I don't have enough power to get the starter motor to engage, let alone get it spinning at all. To this day I'm still trying to figure out how my dad wired up the alternator, even he doesnt know what he did, it was mostly trial and error and bursting batteries. The only way I was able to get the truck started was using a jumper pack to get to 12 volts on the battery with the key on and then running a wire from my battery to my starter by hand. After it started the alternator charged fine but I can tell something was still drawing enough of a load to make me only able to run the cooling fans, lights worked, they were just extremely dim and my turning signals were cycling very slow. I've had this issue quite a few times, and I'm starting to run out of things to fix or rewire.

Well lately I've been having issues with most of my accessories in my 71 521. The electrical has been randomly modified over the years with a few add ons like: 105amp?(unsure did swap about 3 years ago) gm alt. dual (unknow amp) electrical fans(wired to battery, runs on toggle switch, and yes fuse protected) completely new stereo(wired to battery) Lots of small rewiring to get me or my dad home over the last few years. At least enough rewiring has been done to make the wiring diagram a large headache to use to trace anything thats not my lights or igniton. Anyways, today i was happily driving to work, had the fans running, stereo on, and ipod radio thingly for tunes. it was running fine until i turned on my markers and hit a large bump. Stereo goes out, markers die, I almost got ran over by a lifted silverado so i can assume my brake lights died also, and cooling fans run about 1/4 of what they usually do. So i go ahead and turn everything off but the fans, and those get back to about 3/4 capacity. I get to work, shut off the truck and pull out my multimeter. No blown fuses, no burnt wiring, and got full 13v's over my fuse box, give or take 1/2 a volt. I go to key on and everything drops to 8-9 volts. My fuse box is soaking right now in some vinigar. I also forgot which systems are hot on key on and run. The problem isnt in my ignition circut as far as i can tell. Has anyone had a similar issue recently? I can also post pics if need be, just tell me what you need to see.

Put new drums + pads in today, shined the wheels a bit. Preety productive day. :)

Is be good for a set.

It looks preety good, I just don't like the red and thats my only complaint. Anyways its a very good concept and I'd love to see it in a car.
