yeah i thought that the sheetmetal was the same, but wanted to confirm, i know there is a million ways to build one of these trucks,especially if money is no object, mostly i'm curious about the frame and what kind of "hotrod"stuff is available for the chassis'of the 1 ton.up here where i live there are not a lot of 5 window, 4spd trucks that i have seen, and that is why this particular truck caught my eye, so i guess a frame swap to a 1/2 ton wouldnt be the end of the world, rather than hacking up a good 1 ton.anyone else???
