You want the -0050 rear drive shaft...32 spline, small u-joints 10.3k

Yes and no...you have to have new straps for the output yoke on the TCASE, they are not the same as the 218.

At the tcase...the pic of yours shows it's missing, 86humv has them.

And a simple google search "hmmwv 242 transfer case mwo" turned this up. page 2-3 http://psmag.radionerds.com/images/d/d3/PS_Magazine_Issue_565_December_1999.pdf

Oh, you need a new Tcase shift lever....the 218 and 242 are different.

Norm thats the late style Tcase, so you will need the new rear drive shaft that has the larger spline count, you will need a new rear diff yoke for the larger U-joints on that shaft. You will need a new Mid-shaft, you don't need a front drive shaft. you will need new Straps and bolts for tcase...

The 242 upgrade is part of an upgrade kit...includes the Tcase lamp, wire harness,drive shafts etc....

Look in the TM the part might be a 2520012003096 it lists 3 shafts based on Tcase. You have to look at the UOC "use on code" to see which truck applies. when I order, I just tell them what I have...I let my parts guy do the leg work. but I have done older small front yokes on 256...

yep...gonna need that too. Its the same as if you were going 4L80E and 242, the front yoke is larger for the 242. if you stick with the 1330 's for the front diff, you can keep the front/front drive shaft with carrier bearing. when you go with the larger front pinion, the carrier shaft changes...

Just change out the yoke on the diff....they are plentiful. I would not go smaller u-joint.

Yes, later model.....so you need the fatty. They are a little more expensive then the early model.

It just depends on if you have the new style or old style 242. Post a pic of the tail shaft. The older is a 3 bolt, the new is 4 bolts. The spline count is different on both. Once you find the tcase type..getting the PN is easy. I have both in the shop, the old one is slimmer on the slip yoke...
