Jim, I don't have the SA blue prints of the exact measurements and their reference points scaned so I can't post them just now. However Branda sells a manual with smaller versons of the same blue prints if you want exact measurements. You can go by photos like we used to do from old original pictures but that would be a good guess and the blue prints show exact. This manual would be a wise investment to save time in verifying various aspects of your GT350 restoration and I would suggest it's purchase to anyone doing a 67 Shelby restoration. Bob
