It's all out there fairly reasonably priced on eBay, in salvage yards, and in the For Sale areas on the different forums. (Most of these pieces came off either this board or Rennlist.) You just have to move fast before I grab it first.
This is my spare stash here at the house. (Sorry - not for sale) I've got more in the shop and several of the cars pretty well loaded with it. It's nice, but it really doesn't go with every interior. It tends to laminate and crack if it sits in the sun too.
