Depends on what you mean as "complete"....... the seat covers, door panels (in white, dye to suite), head liner and carpeting are available. You'll have to look for NOS or good used dash pads, consoles and all the misc. trim.
Well i would have to completely agree with tim on this all my searches for my 73 XR7 have been for interior quarter trim panels and other misc panels. As all other pieces can be purchased from most cougar catalogs.
This will make you sick, I have a frend that I was going to try and get his extra ginget interor trim from. I went to talk to him sunday and he had just goten back from a dump run and dumped the parts! All were nice! Da&^% I wish I had talked to him a few days earlyer. I thought he knew how hard it was to find this stuff in good condidton.
Well after looking in my catalogs seems that all have just about an equal amount of items for the 72,except Kens cougars which has the door panels and dash cap no dash pads available in my catalogs.Oh and by the way I've never seen any rear panels in a catalog as well.
