Thanks Steve, that is what I thought. The 1960/66 Chevrolet and the 1960/62 GMC used the same seats, the change came in 1963 for the GMC which used a track system.

I would like to see the seat mount s for both types. I have what I believe to be Chevrolet and early GMC, but was told they did not fit the chevrolet. Anyone have any pictures of the seats mounted that show how? Thanks
