Hmm...I have a similar idea for my '53.
Not planning on a dually axle, just a 2-wheel drive platform. Suppose it would be easier to just get a 3500 frame / axle combo rather than modifiying the existing one. The only real headache I see is that the late model axles [1975-2000] are at least 8 inches wider [wheeltread] vs the stock '53 axles. I am thinking of building it with a 1 ton chassis, having owned both a 1989 4Dr and currently a 2000 4dr P/U, and want to make the "little truck" strong enuff to support a short-side dump bed. Ya never know what you will be carrying, so make it strong enuff to do the job in the first place. I also was wondering if anyone has tried to add metal to widen the front fenders, so the wheels don't stick out 4 inches. This would be a eye opener for sure if it can be done. Or are the fenders the same for 1 ton and a 1/2T cab, like they are on the Ford AA and Model A pickup Trucks?
I admit this is more custom work than a stock reassembly would be. The '53 is completely disassembled down to just the frame and axles, which makes it more fun and challenging to put it together as I see fit to.
My goal is to build it up with General Motors parts in a GMC truck. Lastly, does anyone have an idea where I could get a manual steering box, from and American-made car or truck?
