OK I've been doing a bunch more reading/searching. I think my main problem was looking too much at SRAM GXP cranks and confusing with BB30 cranks. (FWIW I don't think the SRAM website is that great in pointing out the difference). At any rate I couldn't find a reference there to my specific cranks:

Here is the NDS side crank:



But in the end I see the same exact bearings are used in the BB, 6808 30.0/42.0/7.0. The only difference is because of the plastic cups on the PF30-68, the overall assembled size (to the outside of the cups) is 71 but obviously the spacers / wavy washer only contact the bearing not the cups so that isn't an issue (as long as the spacers allow enough clearance for the cups).

Also I take it isn't possible to replace just the bearings in the cups, you need to replace both together? (Not looking to do this, just curious.)

Thanks again for the help.
