    What year truck cabs are interchangable with a 79 3/4 ton 4x4? Also, was the rear end in the 79 3/4 ton with a manual trans and NP205 a 14bolt ff?

    As long as you keep with a 4 wheel drive cab from 73 thru 87 you will be good. the hump on two wheel drive cabs is shorter that 4X4 cabs. You could use a 2 wheel drive cab, but you would need a body lift.

    You can cut out the hump on a 2wd cab and put the hump of a 4wd cab and you don't need a body lift. I know, because I did it.

    I've got a 2WD cab on my K30 with TH400 and 205. Previous owner put it on after a roll over. It's tight, but it fits. I don't know if other combos fit, but mine does. However, I would prefer a cab with a bolt in tranny tunnel. Better for obvious reasons.
