930 Ring and pinion, considering something "not recommended"

I'm very unhappy with the sounds coming from my A.M. Engineering (made in Italy) ring and pinion gears. It's been a long effort to straighten out the muffler, sound pad, interior sound proofing, and the speaker holes into the wheel tubs. Now that I have that noise under control the singing ring and pinion is the loudest thing in the car. It's about 10% higher ratio than stock. I don't need the additional revs as I have a pretty wide power band and first gear with my mods is essentially just for spinning the tires.

I have the original Porsche parts including bearing still pressed on the pinion and the bearing race. I found a receipt for syncro work, but nothing on the R&P at all. I suspect it was just installed without regard for shimming and that this accounts for the noise. I am sure that with the factory tool up over $2500 that having it done by someone with the tool will be expensive.

I wonder if, given the odds that nothing was changed to set the preload on the new R&P, I could simply install the original R&P and have the correct preload? Has anyone been into one who can tell me what the chances are of a correct setup?

I'm not afraid of transmission work, but I don't want to have an even larger problem on my hands here. Ideas? Suggestions?
