Of course your best bet would be to look for NOS ones. Even if you have to buy them 1 by 1. I did that with my 69 Dart. It took me several months to put a set together but I finely did. In my opinion all the repo ones are crap. If the car's owner is on the fence about putting them on the car or not, let him be the one to look for them. I do see them from time to time on E-bay. Sometimes just a single, sometimes two, and occasionally a complete set.
