The front of the narrow car was 185 mm. The rear was wider at 200mm. That 76mm hole spacing is very close to 3 inches. Chances are that it is 3.00 inches.
Boomer-I have had this chassis flex discussion with the touring car guys. There is a little magic in chassis flex that you cannot obtain with the shocks and springs. I think that it is because it can absorb some bumps without stiction. The chassis acts like a flexure. This is not a problem on the full size cars as generally they cannot make a chassis that is too stiff for asphalt without a big weight penalty. A full size car chassis that is too stiff for dirt oval can be made.
