Bbp axles with bearings

The hub offset is shallower than BBP by approx. 1/4~3/8" and I think the center register may be smaller too. I have some BBP truck axles I can measure and compare to get exact differences. I haven't done any research on rear discs so I'm not sure if they'd work either or if there's an easy way to tell. I'll measure things tomorrow and let you know and you can check to see if it looks like they will work with the brakes your looking at.
