89 GT interior rear quarter panels...

I'm wondering if anyone here has any interior repair experience here concerning the rear interior quarter panels on the convertible? It has some type of vinyle material coving it. I need to fix both sides on my vert when it comes back from the shop and was wondering if anyone knew what material I would need to look at getting and how to recover the panels? I'm working on changing the color of the interior also to black. I plan on replacing the carpet, seat covers, possibly the door panels, and painting or dyeing the rest. Any experience in this area guys?

Sounds good. I'll check with the local body guy and see what he can come up with. I was hoping on doing the interior work myself with my wife. She's a no sewing fool and we were going to do something a little more custom to see if we could get a different look than everyone else.
