Just an addition too what has already been added. My buddy has a hard time finding aftermarket parts... He'll call shops that advertise parts for his car yet they'll never have anything on hand, plus they'll never get parts in when they promise. This isn't any one specific shop, but seemingly ALL shops.
Also if you're used to working on your car, then be prepared for some frustration. His Helms manuals were $300 I believe, plus working in his wheelwells was very cramping and the midengine design isn't exactly easy to access too.
Didn't mean to throw cold water over your dreams, just wanted to prepare you via some observations I've had.
BTW: here's a pic I took of his car the other night
