SBP axles to BBP

Yeah, I just skimmed thru the above article. Sounds like a lot of bs...all this for 15" steelies...
I went with the Dr. Diff 5 on 4.5 axles and re-drilled drum package, but they're still boxed up because I'm 2nd guessing the green bearings that are already on it. Just a personal p.o.v.
