I'm sure of those two. 69 road runner has a rectangular side marker, 68 had round, and 70 was completely different. Hood gave it away for me. The 55, well I've had a few tri-five's and you get to know them pretty easily. I said Marlin because of the fish. They were aluminum. I would guess the convertible is a 64 Fury? Just a guess...I managed to zoom the picture in more and I think you may have won the prize on the '69 Roadrunner guess.
