Im not understanding the 'all or nothing' attitude? sometimes, a reproduction part is all that is available. with my roadrunner, I tried to locate as many NOS parts within reason and when there was only accurate reproductions available, why not use that? take exhaust tips for example, reproduction 71 machine gun tips are very nice and NOS ones are almost impossible to find. sooo in that case, should I have just went without? seems like stupid logic to me, but hey, what do I know...
