I've been looking all over the place to find a replacement cover and foam padding for the bottom part of my driver's seat in my 1990 K5. Chevy doesn't have them and neither does LMC. Any ideas where I can get them? I really want to keep the original seats because the rest of the upholstery is in excellent condition. I have the infamous rip in the driver's side seat bottom. BONDO WILL FIX ANYTHING!!!
