Ok the RR wave 1 stuff is pretty easy to figure out. The earlier one have skirt's and the later one's don't. As you can see from the picture's you have a Pink 47 Fleetline, and a Green Flamed Suburban. Those 2 are a bit harder to find. Those I think never came without skirt's. There's a lot of variation that I may not know of, but this here is what I do know so far.
1-47 Fleetline with Skirt's "Pink"
2-47 Fleetline with Skirt's "Gray"
3-47 Fleetline without Skirt's "Gray"
1 -57 Suburban with Skirt's "Black with Green Flame's"
2-57 Suburban with Skirt's "Black with Yellow Flame's"
3-57 Suburban without Skirt's "Black with Yellow Flame's"
1-60 Impala with skirt's
2-60 Impala without skirt's
