FAB 9 Inch Assembly Axle Installation

[jr421]

Hi

I finally have sometime to work on my car and I am trying to assemble the rear end and was hoping someone could help me figure out whats going on. I have photos so please look at them too. Let me start with describing the picture, it is showing the axle slid all the way into the center section. The limiting factor seems to be the bearing pocket in the axle tube, it measures .6125" and the bearing width is .8250". I am running wilwood brakes so I tried installing the backing plate and the reatainer and the assembly still doesnt flush or get close to being flush. I have two retainer plates one that came with the brakes and one that came with the axles neither of them allows the backing plate to become snug. Any ideas?????? Any help is greatly appreciated.
