Kind of a terrible picture, it supposedly came out of a 69 Buick GS but I've had people say maybe a Grand Prix. The GS/Chevelle/Olds A body bucket seat bottoms (69-72) all had a different piece in them where a release mechanism hooked to allow the seat to fold forward. This seat does not have the piece where the release mechanism from the seat back(top) attaches. It's my understanding that some Grand Prixs may have had some type of inertia driven lock so no central seatback release was needed on some. Any ideas? Thank you as I am not real well versed in Grand Prixs. Tom
