Ok I’ll start over. It’s a 1972 Chevrolet K20 ac cab. The previous owner put a 6 inch lift on it with 35s. I’m not the biggest fan of the lift but it works. I bought the truck without a motor, transmission and transfer case.

I had a 1987 TBI 350 that was rebuilt with a slightly bigger cam and a set of vortec heads and is converted to a carburetor. The transmission is a 1987 turbo 400 with a 208 attached. Both were rebuilt.

The one of many issues I’m working through is the crossmember will not bolt to the frame due to the transfer case hitting the bottom of the cab. There is an approximate 1.5 inch gap.

I’m not sure if they make a shorter mount, a body lift or a spacer to make up the gap.

Sorry about the confusion.
