where would you try next?

If it matters, "A" only(or 4L) size belt (everybody has went to dual A
and B on same pulley), 3.15" OD, two groove. The old broke one has a
QD bushing, I'll take one with 5/8 bore.

It is an a-b but should give you your diameter from the a only pulley.
Unless you are limited by OD.

I am confused. I thought the two groove pulleys can use either two A
size or two B sized belts. I can not imagine anyone making a pulley
that was two groove with one groove for an A size belt and the other
groove for a B size belt. I think they list two diameters because the
pitch diameter is different when used with an A or B size belt. Look
at your Grainger catalog. It lists a single groove pulley of 3.15
outside diameter and lists A and B pitch diameters.
