i was putting on my seats on the 71 and noticed that the mounting holes are a bit different than my 72. The passanger side is identical. The driver side is a bit different. The front two feet are similar. The rear mounting feet are different. there are 4 holes for each rear foot on the 71 body, on the 72 body there is only 2 holes to mount the rear seat feet. Anyone know if the 71 mounting brackets are different than the 72. can anyone verify this?? thanks, ARQ.
