bonyardboy, I sent you via e-mail a 1973 and 1974 carsets I created along with appropriate carshapes for each season. Not sure if the skins are those by artuco that you are looking for.
Arunas4, have not forgotten you. Bonyardboy has requested some additional skins - season carsets. Do you want just skins or entire season carsets? Carsets have all artwork, etc. Do you want all skins/carsets from 1971-1995?
