I have a 69 convt xr7 with leather black seats. I would love to restore them to there original glory. has anybody have experience doing this. I heard it pain and better left to a pro! How much does this cost? Is there different quality in different in repro upholstery kits out there? If so which is the best? Should I upholseter the back also? Its in good condition but will the new buckets match? Just a few questions, It is something I will do by summer. Thanks!!
