I've been doing a bunch of research and I've determined that this frame is a 1960 to 1962 Chevorlet 1/2 ton truck frame. The length of this frame is a little over thirteen feet bumper bracket to bumper bracket. The body is exactly thirteen feet long!!!! This thing is short!! From what I've read the torsion bar front end was done away with in 63 because of the cost of production. The rear ring gear was stamped 1962 GM. I was told this was a 63 when I bought it but I'm starting to think it's a 62. Unless they used left over parts to build these. Apparently the bodies were made by The Union City Body co. And this one has a decent amount of rust in it but nothing too far gone. Most of the rust is in the lower 4 inches of the box. Anybody have a 60-62 Chevy short bed truck? Is it torsion bar. Approx how long is the frame?
