UM525B is the BB tower, it's a little taller and there is a slight difference in the spacing of the holes relative to the centre line. UM525B is just an updated version, I think with a slight material / durability update.

You are correct to a certain point.
The new BB tower is taller and although the holes on the top are slightly narrower, they keep the same angle of the shocks. Taller = they got to meet sooner or later!!!
Nick is also correct on the screws!
If you use little shocks with the 525 then you have to do 2 things.
You have to make sure you dont have too much up travel as the wishbone will hit the bulk head. You will need to put a spacer of around 2mm to limit the up travel.
You will also discover that you also don't have enough droop so you will have to put a longer ball end on the shock shaft.
I have actually added an ever longer one on the shaft and wound it up so itacts as my washer for the up travel
Hope I haven't confused everyone. - LOL
