I have reworked the VRC Chevy GTO using CSP. there are minor changes on the exterior of the car. The majority of the changes will be in the interior. I really did not like the metal texture on the interior so I gave it a bit of a texture. All the tube roll cage was reworked. A few of the skins have colored roll cages so it will break those. Plastics and other metal bits will have been reworked as well.
Copy the ext_config.ini into the car extension folder. Make a backup of your original first!!!
