67 to 77 frame swap

[Chops1969]

Does anyone know what kind of mods need to be made to a 77 frame to accept a 67 body? Both are stepside, shortbeds.

if it is a 2 wheel drive, then forget it.
4X4 is doable.
67 - 72 have a flat bed, the 73 and up are anything but flat.
After shortening the wheelbase a little, you'll need to make a custom built lift kit to raise the front half of the cab, and then the front clip also. Then there's the mount locations and everything too.
