The transfer case on Jeeps is not a divorced unit- it bolts to the transmission case in place of the tailshaft and housing. Relatively few Jeeps (U.S., anyways) were built in 2wd configuration, so finding a slip yoke tailshaft/housing/entire transmission would be an adventure.
Agree with the 5.2/5.9 magnums, but don't know how readily available they are in NZ.
