\'83 and \'91 mounting differences Alright, I'm looking at major or minor snags I will catch when swapping motor, tranny, transfer case, and springs from a '91 to an '83 k5. I know the wiring harness is going to be different, and will probably have to swap the entire thing to the '83 for all the TBI stuff. As far as the frame goes, will I catch any snags like np241 crossmember doesn't directly bolt to '83 frame, or the spring bushings will need a different sized bolt than the '91 did? I'm pretty sure the gas tank will have to be swapped, but not sure about anything else. Any info you have is greatly appreciated!!!
