Great starting point. I was looking for a chevy like yours when I came across the Ford I'm working on. I think you'll find that the 1 1/2 ton axle is wider and heavier than a 1/2 ton axle. I would recommend a late 50's / early 60's chevy straight axle. It will make your life easier in the long run.

Yep, the whole works is bigger and heavier, as far as the frame and running gear goes. I have an identical truck, except a 1945 1.5 ton. The end result for mine will be close to what your looking at, only it's going to be shiny, and built as a dually. The 1/2 ton running gear is lighter and smaller than what you will have. You'll find the sides of the frame have large plates riveted to it to increase the strength, so it could be classed as a 1.5 ton truck. I plan on removing mine (side plates) and see how bad the rust is behind the plate/frame. I know rust has formed in there, the plate has a few 'wows' in it, but the frame looks uneffected...so far. I've toyed with the idea of dropping the front axle, but it's a big heavy bruiser, I don't know if I can. There's lots of frame length there, so it can be 'Zd' without any problem. Then again, this stuff may be to heavy for what you have in mind, and a custom frame, and different running gear would work better. That will depend on what you want for a final end result. The one cool thing about the stock frame is the depth, being as tall as it is, it would except a healthy notch for the body to sit in and still retain lots of strength. And if boxed, even more so. Channelled without moving the floor up, how cool is that? I'm interested in how you will proceed, keep us informed. Sniper

Steering box and column shouldn't be a problem if you don't mind manual steering. Spindles are going to be huge on an axle the size your looking at. King pins won't be anywhere close to the same size. The drum brakes are quite large being 1 1/2 ton, may have a hard time installing a 15" rim over them, considering it has 20" rims on it now. Then there's the fact that parts haven't be made for it now for over 60 years, might be a bit tough finding pieces if you need something. Not trying to rain on your parade, but you might want to look at keeping the same parts, from the same donor vehicle if at all possible. (Axle and spindles) That way everything matches and is sized properly. You'll need to decide if you want to stay with the parallel spring set up, or go with the single buggy spring style with a lighter front axle. Decisions, decisions, decisions!! Sniper

Just an after thought, what about a tube axle? Find suitable spindles and build the axle to match the spindles, and the suspension style you want? Not trying to spend your money for you...just throwing it in there for consideration as another option. You may be able to go disc brakes if you like. Sniper
