We just bought a 84 K10 Silverado that we are restoring. We searched for a long time for a bench seat for the truck as the other owner had replaced the original with bucket seats. After much searching we found a 79 seat. We have the seat installed, but it will need reupholstering. I would like to make this truck as original as possible and was wondering if I could buy the foam and upholstery kit for the 84 seat to fit it, or if the entire frame of the 79 seat was different and would not work? I know the seat in the 84 has the seat belts coming through the seat rather than behind it like the 79, but I think that is the foam difference rather than the frame. Anyway, my question is can I replace the foam and upholstery with 84 parts or do I have to stick with a 79 replacement kit? Thanks so much in advance!!
