It's been a while since I did mine so I don't remember the details, but you need to disconnect the 4WD shifter from the main case. You'll have to go inside the main case to do it as there's a link or roll pin that retains it. It's not hard to do, just messy. You'll end up with rolller bearings everywhere by the time you get done. Once you get the main case disconnected, you'll have to disassemble the range box to completely remove the 4WD shift rail, but leave the shift lever in the range box case as it seals the range shift shaft.
Depending on where you're getting your adapter kit, they should only need the output bearing retainer from the range box and intermediate shaft between the range box and the main case. It's best to call the vendor and ask exactly what they need.
When you disassemble the range box, remove the retainer that holds the idler shaft in, then pound the idler shaft out in that direction using a large hammer and a soft drift (brass is best.) Be damn sure to watch how the parts come out as there are two thrust washers and two rows of roller bearings with a spacer inside the idler gears that have to go back exactly as they came out or you'll destroy the range box when you get it running again.
