Try finding a newer good driver & set your cab on that chassis. Something 10/15 years old or newer. That would be a nice up grade. Power steering, independent suspension, power disc brakes. The motor & drive-train/ wheel-tire size will all match as a unit. And you will have all the accessory stuff you will need to get it back on the road. Air-conditioning & most of the wiring should transfer over to. Plus everything will be from one make model. You might have a easier time selling your old drive-train as a complete running chassis? The old frame rails may be worn & tired anyways? I wish I had gone that route when I started my 39 COE project. I'd be driving it already.

Car chat means talks about Chevy's. All other car makers only build transportation.
I don't work on my cars, I entertain my self in my garage, so my nabor tells me.
