AW4/Jeep NP208 with Parts Mike's 1" clocking ring (NP219, 228, and 229 from '80 up FSJs fit also but 5" longer) It could also be used with a Dodge NP208 for RH drop front shafts. I think it was originally made for D300 to AW4/AX15 but I'm not sure.

AX15/NP208J

Every v8 came with the 249 and every 93-95 v8 had the 1.55 input. So even if it is a 231 swapped in its gonna have the 1.55.

Lol. I've got local yard inventory that says 95 v6. I think so many of them have been swapped its a possibility that it was swapped. Give it a go though. Having a direct swap case would take 2 hours or so to swap

After adjusting the linkage everything works fine. Thank you for the infos of this thread, it helps me by giving me the kick to do this mod. Ps sorry for my bad english, school time is far away.Dany.
Hi, I've just done the swap on my '98 GC Limited. What did you do for a rear drive shaft?

Some people use the old one, some get the old one cut down by a driveshaft shop, some cut part of the splined end off, and some get a donor shaft from another Jeep.

I personally would get yours cut down to whatever the appropriate length is. That's what I'll be doing on mine.

As long as you don't need it shortened by more than an inch, just cut the slip yoke part of the driveshaft. Save yourself the money from taking it somewhere.

While we are on the subject, what stock ZJ has the longest rear driveshaft? Early v8 has the shortest driveshaft due to the longer 46re tranny, but what drivetrain combo has the longest driveshaft?

My guess would be an early 4.0, but that's just a guess

WHY DIDN'T I THINK OF THIS. I think you solved my problem! I've seen it suggested vaguely before but I haven't heard any body with hard numbers where this works. Now to find something to cut it with.

Well..what's to keep the yoke from bottoming on out on the main shaft? I haven't tried to fit it together yet so I'm not sure how much I'll actually need.

I can tell you this: I trimmed about an inch off mine with a reciprocating saw. I have had no issues dropping the shaft or having it bottom out. I've wheeled it pretty extensively to test it. I don't think the shaft would travel enough on the output yoke on the transfer case. It only moves roughly an inch, if that.

Was this before or after you lifted? I'm on a stock lift at the momment on a 98 Limited. Upcountry package so that's what 1" lift above normal?

After my lift and aftermarket control arms. The control arms will make a difference in the required length as they place the axle in relationship to the vehicle differently. Regardless, I highly doubt the output spline on the transfer case would hit the shaft. You'd require more droop than the shocks could handle to accomplish that.
