The frame and cab need to be replaced on this truck and I have a 1/2 ton long bed frame available but not sure if they are interchangeable. | | | | | Joined: Sep 2006 Posts: 3,596 'Bolter | | 'Bolter Joined: Sep 2006 Posts: 3,596 | They are completely different widths/set-ups due to the suspension pieces. | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | Chevrolet or GMC? If it's a Chevrolet, there was not a long wheelbase 1/2 ton until '55 2nd. GMC did have a long 1/2 ton on the '47-'55 1rst body, but I'm not famialiar with them enough to tell you what the differnces were between them and the 3/4 ton.

It is in the rear where the major differences occur due to the heavier rear differential and spring set-up. | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | That's why I didn't want to really say one way or the other, since I wasn't sure. On the '55-'59s, the long wheelbase 1/2 tons and 3/4 tons use the same frame.
