That is my race car. More like a street strip car. I purchased that car in July of 1990. It's an 04C X22 SS/RS 71B 712 interior BDY 308602 invoiced to 32613 on 04/25/69. I think the data on this car helps support the brown car. The car was a gutted race car when I bought it but it wasn't tubbed. It had a dana 60 on housing floaters with ladder bars and an aluminum head 454 with a glide. The rear quarter lips were rolled to fit a 30 inch tall slick. In 1991 I had two new gm quarters put on it and the car was put in primer. (Still have the receipt for the quarters-$500.00 for the pair) The tail light panel had charging lugs drilled in it because the car didn't have an alternator. When my body guy did the car, he repaired the lug holes but left these three other holes in the panel because he thought they were for a camaro emblem. After I found out about the brown car, I measured these holes and sure enough they matched the other car. That was then confirmed by the NICB. The car is still in primer.
