Well you know you don't have to swap the cab. The front clip and doors will bolt on to the 68 and you could just transfer the trim. You'll have to paint it anyway because the bed on the 71 is a lwb. Then you keep the AC and get the Cheyenne look. The VIN could stay the same as the 68. It would be cool to modify the 68 hood and keep it as well. But that's my 2 cents
