What I would do is check out your local junkyards for bucket seats from a 1979-1991 Suburban, Blazer, or Jimmy. Sometimes the crew cabs of those aforementioned years had front bucket seats, too. Maybe you'll luck out, and find something with good foam, and you can get a reupholstery kit from LMC truck. Even if you walk away with the skeletons of those seats, it's better than nothing. You can get them refoamed by a professional or yourself, and then get the reupholstery kit. You can also start a new thread saying you want some bucket seats. Maybe someone on here can hook you up. This forum is an exceptionally vast resource.
