Chevy is abundant for one reason only. People spent money for products offered. The old mopar saying, mostly old parts and rust is why stuff is limited.
Chevrolet/GM have always had a larger share of the automobile market in the U.S. than Ford or Chrysler. Having the numbers of people willing to buy products is a plus, can't argue with the economics of it. The restoration market is the only place i see an abundance of parts for older Mopars.
