I will always try be first in the line to get what it correct information on things. To misrepresent to anyone such as this is embarrassing! In my exploring I have seen so much information on the first generation of Firebirds, I wondered at points what really was 10% correct. This data you provided I believe is most correct, as the car came with Upon my Purchase, a Rochester "mid section" XXXXXXX64 that is currently unusable. Yet I have acquired a good XXXXX64 Full carburetor since, along with several xxxxxxx68 full carburetors. This is my saving grace here I believe, having this components on this matter. Your information and sources are very Valuable to me and I appreciate it much. This is a golden moment that makes us all have trust and integrity!!! Very appreciated! Rob
