Can you help me identify what seats work in the 60-66 Chevrolet suburban and which ones fit in a 60-66 GMC suburban? I have a couple of seats thatI am in the process of selling and I have some confusion on which ones fit in which make. I had a guy come by in his 60 Chevrolet suburban and tell me they were not the correct ones and another guy come by in his 64 GMC suburban and we could not make them line up either. I know they came from a 60's suburban, I just don't remember which make or year, I pulled them myself. They have the tube support with holes that had the flat bolt and wingnut to hold them to the floor.

I thought that these came from an early GMC suburban, which to my understanding would fit both the Chevrolet and the GMC, is that correct?

If you have pictures that show the difference, I would truly be grateful. Thanks..................g
