not sure on the write ups, but i did a 242 to a 231 with a 4:1 teralow
problems i encounterd were spline counts on your output from tranny, to input on the new transfer, now I was working on a 89 XJ, I belive they went to a 23 spline out put on the later years but dont know enuff about the year switch, so splines will be your biggest issue, it will bolt right up, linkedge will bolt right up, but your plate in the jeep telling your shift points are off, the 242 case is a bit bigger I dont belive that creates any driveshaft issues, unless your looking for a slip yoke eliminator, there is not as much aftermarket products for the 242, dont know what your running as far as lift, but if anything over a 2 inch I belive you need a SYE... now when i was doing my resurch on this i didnt find much and what there was for the 242 was not great... thats why i went to the 231 insted, to go with my 5.5 lift, then I orderd a 4:1 teralow and it came with a 23 spline input and I had a 21 spline output on my tranny, now my fix was adding a Klune underdrive, to the mix now I have 2 transfers, lots of gears, I am told that its posible to change the output on the tranny to fix any issues... and now I wish I had gone to a atlas transfer insted, when I blow the 231 thats what I will be doing... dont know if this helps thats what I know... goodluck!!!
