First off,I purchased this fastback as a gutted 70's ISCA "show car".The rear wheelhouses were pretty damaged to fit 31x15 slicks.the original owner had carpeted the rear and removed all seat provisions and installed a 4 point bar (poorly),custom front frame rails and subframe connectors that come up through the rear pan in front of the rear seat kick up. i "repaired" the wheelhouse damage by fabbing my own tubs.After trying to fit three different rear seat setups around the bars ,I removed them.So I finally fit my rear seats to the tubs (neon buckets w/heavily modified frames)forgetting about the tunnel offset but pulling it off anyway.Since I had no front seats I modified the base mounts on another set of neon seats and made a rear riser to level them out a bit.they are equidistant from the rocker flange at 5-1/2 " to the rails.the cushions are almost 4 inches to the flange.The pass seat is as centered as it can be and the drivers seat seems offset from the column mount.there is 10" between the seat cushions and the gap at the tunnel is noticeably different . I'm also not sure if the seats are to close to the firewall .The measurement I took is from the column hole to the cushion.I'm also not sure of the factory cushion height.Could someone supply me with measurements . As long as I'm in the ballpark I can move on and paint the jambs. Thanks in advance.Keith
