Can anyone tell me what year these seats are?

 

All I can say is they are 66 up GM strato(?) buckets. Don't know what year or make (maybe Chevy) the upholstery pattern is except not 66 or 67 Olds.

 

1967 buick Rivera I beleive

Frames are the same as A-bodies-The side release and metal sides and backs means they are from a 67.

 

Side release was to up to the end of the 68 model year. The pattern isnt Olds for sure. Didnt the late model year 67s get plactic backs? I thought I remember someone here clarifying that question a few years ago? Anyone?

 

They aren't rivi covers... I know i've seen that style before, but can't put my finger on it.

Regardless they are 67 Frames & side & seat backs, and will take any GM A, B or X body bucket covers 66-72

I can't answer the question about late 67 seats getting plastic backs or not... but i can see in the pics that those are metal for sure.
