It's for 3 different cars. The moonhawk, barstow, and D-series. The D-series skins don't show up for me but the other two work. Do any of these have skins, and did you put it in the mods folder?
Hey, this stuff is great! I hope to see some skins for the Bluebuck and GM; consider this followed! (It'd be interesting to see something like the Wendover with this IMO.)
Also not gonna lie, trucks skins from this mod is the near perfect replacement for that dead D-series NASCAR mod.
