I've tried a couple via phone. Unfortunately, the places I find are standard junkyards. If it's more than 15 or 20 years old, it goes to scrap. Peters went away 30+ years ago.
I'm sure there are "know a guy" unofficial yards down that way, but I don't know a guy and it's 3.5 hours one way just to attempt to find a guy. Where do I start? The Chamber of Commerce? "Hey, I'm not from this area. I'm looking for old Mopar stuff, but I don't know a guy. Do you know a guy?" (I'm not trying to be a jerk, just pictured the scenario and thought it funny).
Actually, now I'm thinking there's a someone locally who might know a guy... at least, he might know a guy that knows a guy.
In all seriousness, thank you for responding. I wouldn't have even thought of him had the above scenario not played out in my mind.
