I put a pair of seats out of a grand prix in mine. Got them for 50 bucks. I was able to drill new holes in the drivers seat and attach it to the power seat mudule, so that I still have the original seat controls. The passenger seat took more thought than the drivers but worked out. Since then I have rebuilt the seat frames so that they would tilt forward for access to the rear cab.
I just had to pull the seats out of the truck and start measuring. If you are lucky everything will line up without to much work.
