So, should we just use Ø4mm pin for A-datums? Also, does that mean we should use (5.07-.20)= 4.87 pin for C-datums?

I am attaching a simplified part drawing that I have to make a checking fixture of. Following are my queries: 1. I was thinking of holding the A datums using 4-way locator pins (conical), so both holes are concentric but then I realized if I do that, how would the part touch the B-datum, what...
