What transfer case do I have?

[Willy]

New to all this XJ stuff and have some questions.

The transfer case in my XJ is different to my TJ. I now have a Full-time 4wd mode in high range. Does this mean I have a Selec-Trac or Command-Trac and NP231 or NP242 transfer case?

Also, where can I get tow hook brackets from for the XJ? I have seen a few write ups where you need a bracket to put the hook on.

Thanks.

Selec-Trac = NP242 = NV242
Command-Trac = NP231 = NV231

I mention the NP & NV thing becuase they are the same box. Originally the name was New Process, then was changed to New Venture...but the same box.

Although the 231 t/case was used in some XJ's far & away the most had 242 cases.
TJ's & YJ's used the 231. I believe the Diesel XJ uses the 231 too....

What's the diffenrence in systems? does selec-Trac have an additional 4H (fulltime) option?
if so can it be put into a wrangler without too much fuss? what box(es) do the new cherokees have?
