desperately need advice of how to modify seats or replace them. got a '97 s10, 3rd door that the seats have been in the upholstering shop twice and the problems get worse. no padding or padding rolls in the middle underneath leaving metal to support butt. shop says its a common problem w/94-97 s10s. would love to replace seats, but have no idea how. i'm 6'6" tall and can't afford seat too high of floor, but no lower either. some please share valuable advice.
