First Gen Camaro CG Height?
 

I was wondering if anybody might know the height of the center of gravity for the first gen camaro? Specifically 67, but I'm going to imagine the first gen cars were all pretty close to having the same dimensions/weight distributions. Or if anybody has any technique for finding the CG height, aside from tipping the car (already heard that one), I'd be very interested to hear it, and any help is appreciated.
Thanks
