My 73 seats are in great shape, but they lean back way too far. I've had the tracks out and they are good and straight. I've checked the spool pieces that clamp the seat back in place, they were a little tweaked but now straight. There's no play in the brackets, I've gotta think that the seat back frame may be bent up above the bracket. Both seats have the same lean. What do you suggest as a replacement from a newer generation? I don't have a welder but I can do some minor fab work. I need something that would fit the stock tracks or have the ability for me to adapt the new seats tracks. I need to be able to get my seat back much closer to ninety degrees. Any Suggestions?
