i have a '72 Chevelle and it has swivel seats in it out of a mid-'70's monte or grand prix. they are great seats and all, however, i am 6'4" tall and my head hits the roof when i am sitting in the car. you can imagine how uncomfortable this is, not to mention how well i can see. i came across some seats out of a newer f-body that had been wrecked, and they look pretty good. i was wondering how hard it would be to put the f-bodies seats in my chevelle. could i set them back farther than they are suppose to be since i'm so tall? and can i get them low to the floor. i would appreciate any advice or suggestions. also how much should i give for the seats, they are leather and in fair condition?
