Chevrolet GMT400 K3500 Extended Cab V1.0

Work in Progress, BETA, previous upload is broken, lost the original that worked. Body Color Config Bumper Options Color Configs. Engine Configs, Rim color not fixed yet, nor is the rear bumper or attachers appearing. I’m pulling my hair out in attempts to figure out what is causing the issue.
