I think I have some magazines from '67-69 which addressed those cars and detailed articles on the options (which was basically anything you wanted to pay for as I recall)..
PS. Is there any market for a few thousand auto magazines from the mid-late sixties til today.... PHR, HR, CC, CHP, Muscle Car, etc....? I'm going to get submitted to that 'hoarder' show if I can't get rid of these things, and I can't stomach trashing them. I have them grouped/boxed by month/year and magazine...
