bbp axle help!?

Are they doctordiff axles? if they are he sells both A and B/C/E body offset. If your running the bigger bolt pattern WHY IN THE WORLD would you want to run the crappy small brakes? the above B/C/E body stuff bolts on with the correct 2.5" offset axles.

to answer your question the offset is from the housing to the outside of the axle flange
