Found all these yesterday at the Santee annual car show, and it made me happy to remember my Demon, Challenger, and Super Bee. I don't have any of them anymore, but they were great, and brought me along in my enjoyment of Mopar Muscle
My Challenger was a rusty but strong 340 powered '71. http://justacarguy.blogspot.com/2006/11/this-was-primer-gray-phase-of-poor-but.html and the mags I had were 10 or 12 inches wide... damn they looked good
