Does anyone have a reference for interior upholstery suppliers? I had my front bench re-done by a shop when I was back in Pennsylvania and it was quite spendy. I need to replace the fabric on the rear bench seat and seat back. Springs and all are in great shape, just looking for the fabric.(4-door Chevy II) I'm just thinking of doing the work myself and saving a few bucks. Any assistance on this would be appreciated...Thanks...
