a12 air cleaner base measurements

[greycharger]

Would someone measure their the openings of the base and give me the two distances in the drawing? If the distances between carbs are not the same, front-center and rear-center, please note it.
Thanks

Measuring from the side of the base that faces the motor I got 2.265'' on the front center and 1.696" on the rear center.
