Looking up a SYE kit for my '06 Wrangler. Would I have the NP231 TC? Looking at this kit here but it only shows it fitting TJ's through the '01 model year.
I got one of those, and have had no issues. Basically, it is an Advanced Adapters without the name...
By the way, get some GOOD snap ring pliers for this job; it will save you hours, if not days of fighting with the snap rings in the TC!!! (DONT ASK HOW I KNOW!)
