Hello friends, it's been a while since I posted.
When I install mods for GTASA, they don't install at all (for some reason, I've tried uninstalling GTA:SA, and reinstalling it to no prevail.) and this happened when I installed a 1950s car mod for GTA:SA and I accidently installed it on to the Hustler (which wasn't the correct car model? :S) and I downloaded it from http://www.gta-classics.net/. The car model that I downloaded is..
1957 Chevrolet Bel Air Police.
If someone can fix this, then I will LOVE you forever. I can't install mods because of this and I like to install mods for my GTA:SA.
