I have a couple 1986 Audi Coupe GTs that I decided to part out rather than fix up and sell. Between the two there should be at least a whole set of parts available. Let me know what you want or need and I can let you know if it is still available and cost. I will charge reasonable shipping, but it needs to cover packing materials and some time if the item is difficult to pack or bulky.
If I do not get back to you right away you can also try emailing me at bennu500x (at) gmail (dot) com.
