71 demon rear seat--wanted

Your 71 seat should have tabs that bend over to hold the back in place at the bottom. A 73 bolts in at the bottom. The seat I had was a 71 seat with a 73 cover.It was the correct frame for your car with 73 covers. It just left at 1:30 I sold it to a person that picked it up. He had 73 seats in a 70. I tried to sell him 70 seats front and back but he likes the way the 73's feel so he is leaving them in. He bought the rears I had that fit his car. I sold them for $100.00 because they had new covers but on the wrong frame for someone with a 73. I have another set with a simular pattern but not sure what frame the cover is on. I can look for you and take pics but this is the last set.
