Replying to Anybody know how far ill have to move my mount switching from attacks to pivots

If this is a dumbass question forgive me, but Id rather ask here than take them to the shop and have them tell me they need to pull the attacks off to line up the jig and see how the holes matchup. Does anybody know from experience how far the mount position needs to be moved swapping from attacks to pivots? I know the 5mm rule but wondering how the screw holes match up. someone make my day and tell me the screw holes line up perfectly so i dont haev to move the mount position at all
