Rear Assembly Panels

[jefferyzornow]

I have a black 1990 ZR1. I noticed the other day while working underneath the rear of the car the inside body panels (both sides) are tan in color. I know that the ZR1's have wider rear body panels than a regular C4. My question is; were these (tan on the inside) panels assembled at the Bowling Green plant or were all ZR1's sent out to an assembler for modification and returned to the plant for painting? And are all original rear body panels tan on the inside?

Thanks

Welcome to the forum.

I believe the tanish color on the underside is perfectly normal.

Yep, just the urethane color of the bumper. Front bumper looks the same.
