AAAHHHH! Got It. I thought of that after I posted. If you have access to junkyards with vintage cars you may be in luck. Many other Chrysler products from around that time used the same connectors (Full size cars, pickups etc) I've scavenged harness connectors out of 70's vans that were identical to Challenger pieces. I don't have a source for new ones unfortunately. I wish I did, I'm in the process of redoing my whole dash harness currently.
