I picked up some photos from a friend of mine today because there's at least one pic of me anda my wife in front of our GTS back in the 1980s and lots of pics of the car that drove us away from our wedding ('69 GTX convertible).

One set of pics (and the "bill of trade") are of what appears to be two 6 barrel cars (1970 RR and 1970 'cuda) for another '69 GTX convertible. I only know one name on the piece of cardboard the transaction is written on. That's Don Parker (lived in Sunnyvale in the 1980s). The other names appear to be Jim S(can't make out much of the rest) and Pete Stein (I think).

There's more pics if you know the current owners of any of these three. Trade was probably done in late 1981 or early 1982 (my buddy's GTX was running aftermarket wheels until May 1982 and he bought it in late 1980 or 1981).
