Technically you have to adjust pinion depth, preload from the side, as well as placing the ring gear propperly side to side.....
Unfortunately its all done with shims, and you don't have the tools and parts...You can buy shims....but it seem you have to have a special feeler gauge to know what size to order.
you should be able to track down a copy of the FSM on the internet, if not shoot me an email
On the helical that I did I just re-used the old shims in the same places and backlash was the same as before....While its just a guess we were kinda figuring that the OEM diffs can be produced to a tight enough spec that variances aren't that big relative to whats allowable...Meaning the shims are for the most part there to compensate for differences in the large cast diff case. From the few who have just tried it and checked afterwards as long as the stock shims were used in the same place it was fine....
I dont know if an aftermarket would be to the same spec, and I wouldn't throw it all back together without checking.
