Here's something from the MML that I saved for future reference that may
want to consider.
----------------------------------
Actually, the one major advantage that the 9" Ford rearend has over
any other rearend is the fact that it has an additional bearing
support on the end of the pinion that is unique. This extra bearing
virtually prevents pinion deflection, which is the cause of most gear
damage.
As a point of comparison, on the three different castings for the
8-3/4", the difference is primarily in the inside diameter of the
pinion support bearings; the bigger the diameter, the stronger the
pinion is, and the better it is able to resist deflection. The Ford
bypasses this issue with the extra bearing support at the end of the
pinion.
