I can't imagine why anyone would be mad at you. Exchanging info, ideas, and interests is what this forum is here for. Sorry I can't help you on your quest but I do love the cars you are talking about. My uncle had a 340 '70 or '71 Challenger from Mr. Norm's Dodge when he came home from Thailand after the Vietnam war. I loved that car and have always wished I had it. Wood handled pistol grip shifter, doesn't get any cooler than that.
