It is generally known and accepted that GM did not keep exact totals of each model type,option and color of each car they produced.
I have never found a resource to dispell this, but new information comes to light all the time and it may be available sometime in the future.
If you have not visited www.camaros.org (http://www.camaros.org) to read through all their information, I would recommend you do so.
The research the CRG has done in the area you are asking about is excellent.
Here is the link - http://www.camaros.org/geninfo.shtml#OptionCombinations

Hope some of this helps.
