I actually prefer the 71 to the 70. But I love my 72 more than both of them.....because it's mine lol.
I also know how you feel about the swap meet having no mopar parts. The biggest local car show has a swap meet every year and last year there was only one guy that had mopar parts (the same guy I bought my 'cuda from, and I had no use for the model 70 specific parts).
I also go to the biggest car show/swap meet in the state every year. And while they had a few more mopar parts....pickings were real slim.
