No bites yet, so I'll give it a try. You will need the shift gate and label sheet which identifies the positions (ranges), since it is different from the 231 to 242. Others have reported the linkage is the same, just the t-case and shift gates have different positions. You have a vacuum-disconnect front axle- the 242 does not have the vacuum hardware to do the switching. 242 t cases came without the disconnect axle. Options would be to install a manual shift lock (pull cable deal to lock and unlock the axle) or to fix the shift fork in the locked position with washers behind it to hold it in place....others report success, not for me. I like the disconnect feature and the front drive shaft not turning in 2wd. If you ever want to add a locker or agressive limited-slip to the front axle then the disconnect is a real benefit. There have been issues with getting the full-time/part-time lights in the dash to work properly, I'm not sure what you will find in place in the dash. A factory service manual would help you trace the differences in wiring and vacuum sytsem between the two. 4xBob
