it is the same style cab. it came off the same year truck just that it is a 2wd. but it seems like the 2 back acb mounts are not matching up within the same depth range as the 4 front ones. mortition
what will i have to do to make the cab match up to the mounts on the 4wd. which ones will i have to change? just the back two?
In the cab change the 4wd cabs have a larger hump in the middle for the transfercase. I put a 84 model cab on an 77 frame and you have to have a 2 inch body lift and the back mounts are different just build a 1 and a 1/2 inch more spacer and everything lines up fine. Hope that helps you.
