Urrm.... I dont really know about reupholstering. In my case, it was much more affordable to buy a set of salvage seats than have the existing seats reupholstered. There are some places out there that can do this. I'd looked into this briefly, but when I saw the rough estimates of cost heading into the thousands, I quickly decided against it.

Good luck, and let us know what you find out. If you find some place to do it and want a 2nd set of eyes to check it out, post here and we'll check it out.
