So the SBP axles can be redrilled to BBP, then drill the drums too? I wasn't sure there was enough material for that. Interesting, could look into that to keep all of it as is.
Seems to be mixed opinions about doing this. Do a search on that.
Not sure what options Dr Diff has for LBP axles. With the SBP he only has the slightly shortened ones to use with green bearings. The factory length is needed for the tapered adjustable bearings so the axle ends contact the "button" inthe diff.
