I want to buy Ring and Pinion Gear

[Leo B]

Hi, Please help. 
I have Stude Avanti R2 4-speed Spicer Limited Slip (Twin Track) Dana 44. Ring with 10 bolts. Ratio 3.31
I have broken pinion which is 10 spline.
I have asked many Jeep part seller and they cannot help me. All are wrong sizes or at least wrong high ratio.
Dont find from vendors so far.
Im waiting also answers from Dan Booth and Jon Mayer.

Is there somebody who can sell me correct Ring and Pinion?
Is it possible to use other that 10 spline Pinion with new yoke?
