PU parallels the 3B line in foul territory until he is sure R1 is coming to 3B, then moves into fair territory with a good angle to 3B to make the call. BU has tags at 2B and 1B and anything else that happens at 2B and 1B. If I see my partner moving toward 3B I will holler out that I have 3B, but since I always cover this situation in pre-game it's not normally necessary. If I am working bases I generally point toward 3B with my left hand and my back toward home to remind my partner (don't always work with the same guys).

I don't think the manuals disagree on this.
