GM A Body Rear Seat ID

[SuperNovaSS]

I recently bought a storage locker full of vintage car and motorcycle parts. I have been able to ID most but some without part numbers are difficult. Most of the car parts were Buick Skylark. I have 2 rear seat seats that I imagine are GM A body but I want to be sure before I sell them. I believe one is an early 64-67 set and the other is 68-72. Can anyone confirm what these seats are? The upholstery looks original so I imagine I could ID through catalogs or pictures of cars but there is so much knowledge on this site that I thought it was worth asking. Also, if anyone is looking for a seat please PM me.

Set 1(68-72?):
















Set 2(64-67?):















Thanks,


Jason
