Not sure when it was run last. I'd like to rebuild it but right now its gonna have to sit. I still need a transmission and spending that hundred left me $6 till payday.

I do have a couple questions... I took the gas tank off to see if it needed flushing or anything and to my surprize it looked really clean inside. Tank was bone dry with a light gas smell. My question is the filler tube was loose and when I filled the tank with water to check for leaks it leaked at the top where the float goes in and it leaked real bad where the filler tube goes in. Is there supposed to be a rubber seal or something where the filler tube meets the tank and should that top seal be watertight?

Another question... this one about the rear end. I jacked the car off the ground so the rear wheels would turn freely. When I turned the drivers side wheel the pass. side did nothing, and when I turned the pass. side the drivers side did nothing... but turning the yoke (or whatever its called) in the front of the rearend moved the pass. wheel but didnt move the drivers side. Is there something wrong there or is that what its supposed to do? Also how do you fill the differential with fluid? There doesnt appear to be any place to add fluid.

First the tank. That neck isn't suppodsed to wobble, and it doesn't have a gasket. It was originally soldered or welded, and it's broken. Time for a new gas tank.
Second; the rearend sounds like it's got bad spider gears, or a broken gear shaft and needs some work. It should either turn both wheels the same direction, or opposite directions, but always both wheels when they're both off the ground.

you may be able to have the tank brazed at a radiator shop to save some $

I'd hesitate to let anyone braze or weld, or solder on a gas tank! Good way to blow yourself up! Their more dangerous empty than full!

I thought about welding it myself but then I thought of the explosion factor and quickly changed my mind. But.... If it was rinsed out REAL good with water would it be weldable with a standard MIG welder? I'm assuming the tank is galvanized steel (?) so I dont know is its weldable with my MIG.

If it was mostly full of water, couldn't you weld on it? How much could an empty unpressurized gas tank that has been rinsed out and only faintly smells like gas explode? Seems like a long shot to me, but then again, I would probably just spend the $130 and buy a new one.

I've seen tanks filled with water and welded by really good welders, but it acts like a big heat sink, and makes welding a pain. I've also seen the results of tanks that were washed out and then welded. One looked like the Michelin man after a small "boom" that resulted in some soiled undies!
Remember, you'll be working on the area where the explosion exits if it does go poof.
As ATM said, they're only $130 for a new tank, and even less for a good used one. Not worth the chance to me.
