AMC = Mopar?

Correct. Because what you do is irrelevant. If the factory does it, that's a completely different argument. What ever the factory does, it owns, at least until the warranty has expired.
I was trying to make the point that a few Mopar parts does not make a Mopar. And anybody who feels an AMC is a Mopar just because AMC used some Mopar stuff doesn't realize Mopar used GM tilt steering column parts..... Rochester carbs........ Saginaw steering pumps....

I stand firmly by my view that an AMC is not, was not, and never will be a Mopar, and has no place in Mopar shows, magazines, clubs, etc. Don't get me wrong, I like some AMC products. And a few other brands as well. But an AMC is no more a Mopar than a Mopar is a Benz.
