You're better off with nice used on the stainless parts. Wheel opening moldings & rear deck moldings are aluminum and repro is pretty much the only choice unless you want to spend high $$ on NOS. Herb's is a good seller and I've had good luck with Dante's. I'd NEVER spend another cent with Roseville.
Get on Year One's e-mail list and you can get a 30% discount at times. Without it, their regular prices are pretty high. Classic is about the same.
