Cab swap
4 Answers
Yea but wheel bases changed in 77 wasn't sure if that changes cab mount positioning
old thread but maybe this will help someone in the future. I put a 82 1/2 ton cab on a 77 k 30 chassis, there no problems. Cab bolted right up to frame. I used a winch bumper, It seems like there may have been something with the bumper if using original bumper. Maybe the frame rails were not as long out of the front on the older series. There may not be any difference It's been 20 years since we did it, But..... still have it.
