Your options are limited. You can get one of the so-called "hack-n-tap" kits from someplace like Rubicon Express. Tom Wood's is the only company I know of that makes a complete SYE kit for the 242. In fact I have one on my 242. The TW kit still uses a hack-n-tap style but at least they have the machine tools to get it right.
Actually, I just pulled out my 242 (w/ Tom Woods SYE) and replaced it with a 231. The 242 was completely rebuilt with new bearings, seals, chain, and the SYE about two years ago and has seen limited (mostly trail) use. I went with the 231 because it has a bit higher torque capacity and much better aftermarket support (real SYE kits, wide chain, 6-gear planetary). I would consider selling you my 242 but quite honestly I think you should go with a 231. The often cited reason why people want the 242 is full-time 4wd but I don't think you really need full-time 4wd even up in your neck of the woods. Find a 231 from a 96+ Cherokee, get a SYE kit from JB Conversions or Crown Automotive, and you can't go wrong. Chuck & Eddies junkyard in CT has a couple 231's for $60. Worth going on a road trip for.
