[nsantos1]

Im working on my seat and track
My car was originally Bech seat someone put bucket seat and I’m trying to see if this is the correct seat tracks. Only one side have released. The inside track no release. Just free!
Thank you for your assistance.

My 71's have latches on both sides. Having said that, I understand that subsequent models did away with that...Maybe in '72? You can see the window on the inside track in your pic the "teeth" but no lever. Have the levers been omitted by the OEM, or removed by the previous owner can't say for sure.

Looks like you have the 1973-6 tracks.
