Yeah I've sifted through the manual but haven't found any mention of taking up that space that could occur if many shims are required. Unless you're just supposed to install as many gaskets as it takes to take the space up? I guess a proper way to phrase my question would be- is the pinion bearing race supposed to 'float' a few thousandths in the bore or is is supposed to be 'crushed' by the retainer cap? I'm using the exact shims that came out of it so I'm not sure quite what I'm missing. Thanks y'all.
