Bore Pattern True position with MMC

[[Da...]]

I have a part that has for bore ground into the side of the part, with 2 on each side along the x-axis. I am trying to get the true position of the bore using the bore pattern within the MMC.

I am using the Datum A, for one of the constraints, and for the other Datums B and C two are bores along z-axis. I am measuring Datums B and C using a single circle each.

I am processing them as a best fit bore pattern for the 4 bores on the side with no rotation or translation since I am constrained by Datums A, B, C.

Is this the correct method for getting the true position of the pattern within the MMC? Or am I allowed rotation since Datums B and C are orientated along the same axis?
