@krashadam Yea, I noticed a few mods that were taken from here and put on gtainside. The good thing about that site though is that is has older versions of mods that this site doesn't host. As far as the mod I linked, I have no idea how to convert it and was going to watch some tutorials on how to do it. The author hasn't been active for like 6 years so I think I'll be alright if I just give him credit for the convert to gta IV.

@krashadam I don't think the guy has been active for a while. Mod: http://www.gtainside.com/en/gta4/cars/31170-2002-chevy-camaro-35th-anniversary/

What if I want to convert a car from gta IV but can't get a hold of the author?

@Cyron43 But why would you report his post though? Because he worded it wrong?
