Yes, I have a Coronet 440 series, that I probably overpaid for just so I could make it into an M-code car. Thats' the other thing; the seller knew that guys are looking for "440 series" cars to make them into A12's so he wasn't budging on the price very much. Since that's what I wanted, I had to shrug my shoulders and pay da' man.
For what I'm doing, if I can find repop parts, I'll always go there first. BUT, if the only way I can put something on my car is to use an original, then I don't want to hear anyone saying it belongs on an actual A12 car. That's just being elitist.
I guess what I'd like, short of actually owning an A12 car, is to have someone that owns one, look at my car and say "gee, he did a really good job!"
