Hi, I am new here. I just bought a 90 IROC conv. that has been sitting in a barn over five years and hasnt seen the road in close to ten years. It is suprisingly in great shape. I have researched all the places I can find but have come up short on one question. How can I find production numbers regarding color and interior. Mine happens to have red leather with black paint. If anyone can help, I would be greatful.

 

You really can't. The truth is that GM didn't keep track of combinations, and the only numbers available are for some option codes. Take a look at the Camaro White Book, that's about as specific as the numbers get.

You can check www.compnine.com also, but that's more of a parlor trick then anything else, and it's not guaranteed to be 100% accurate.
