3.90's now possible in a Moser 12bolt?
I ordered a 12 bolt housing with 33 spline axles from Moser. I want to use this:
5TT564 Tractech Truetrac Limited Slip 12 Bolt Car (3 series) 33 spline $495/ea (From Moser Engineering's website)
Since this is a 3 series carrier, can I use these from Summit:
RMG-4900401 Richmond Gear Ring and Pinion Sets
Gear, Ring and Pinion, 3.90:1 Ratio, GM, 12 Bolt Car, 3 Series
Please tell me if I can stop trying to decide whether I want 4.10's or 3.73's and that I can do this and just run 3.90's.

Yes you can. I have a Moser 12 bolt and run Strange / US Pro Street gear #RS01888391. This is a 3.91 ring and pinion for a 3 series carrier / Car 12 bolt with a 1.625" pinion shaft. They were the perfect ratio for my setup. Good luck
