SBP or BBP?

From what I've seen, your run of the mill 28 spline 9" Ford rear end isn't as strong as an 8 3/4....especially if you put a big gear in it. You usually have to grind on the housing for clearence in the Ford, making a weak area even weaker. Plus, I don't like ball bearings on the axle shafts. The tapered roller bearings on an 8 3/4 are bullet proof.
