Can't seem to find solid info on this. Full bridged motor with housings notched, 1pc seals a must?

 

Depends on the size of the notch but I would more than likely go with the one-piece seals for safety sake...

 

If it's full notch on BOTH sides then yes 1 piece is a must. Otherwise the corner piece of a 2-3 piece apex seal will fall into the runner. It's the same principle as the BRIDGE on a bridge port. If you don't bridge the gap, the corner piece will fall in.

 

Depends on the apex seal. Some apex seals have corner pieces that are 4-sided specifically so they can be used with bridgeported setups. Depends on how far the rotor housings have been notched vs. how long that corner apex piece is.
