Re: any one made a indexing ring?
I drilled and tapped the t-case instead of the tailhousing with new holes. This allows you to retain all 6 bolts. It took me about 4 hours to do once the t-case was out of the vehicle. Most of that time was cleaning out the case from the drill shavings that went into the case. If you are rebuilding or adding 4:1 gears to your case it would be super easy. Below are my pros/cons to doing it without buying an indexing ring or drilling the tailhousing:
* Free (I had to buy one tap $5 and some gear oil)
* Retain all 6 bolts through the cast iron.
* Index EXACTLY where you want.
* Keeps tcase tight against tranny giving the most contact to output/input shafts. (not that using an indexing ring is bad)
* Time. It took me about 1-1.5 hours to drill/tap and another 3 to clean the case.
* The orginal tcase holes are lined up with extra reinforcing 'bosses'. The new holes are just into the tcase. It can't be any worse than the indexing ring.
Overall I'm really happy with the outcome. I have been to Moab, the Hammers, and have put over 12,000 miles on it with no leaks or problems.
