Ma4-5 flange size

I assume you are asking for the Carb to Intake pattern. 5/16" studs on a square pattern. I measure 2-11/32" square pattern with the calipers. Gasket is 3" square. Picture shown and measurement is from a 6AA carb, same interface. 6AA carb bore is 2-3/16" Diameter. I'm not pulling my MA4-5 to check that dimension.
