Did Jeep ever use the New Process 231 tcase?

Think I have a vacume one kicking around

Were you able to confirm this one way or the other?  I dropped by Broken Axle this morning, and the 231D HD they have is completely different from my 231D, so I'm still on the hunt.

The only vacuum 231 I have:








have a few other t-cases floating around

That looks like it (the vacuum port and speedo takeoff are in the right places, unlike Dave's), but I have no idea what the difference(s) is/are between a D and an AMC.  Would it be possible for me to come by, take a closer look, and compare?

Yes, good to meet.  And thanks for spotting that trans/tcase on kijiji - I snagged them from him and
the tcase is bolted up.  Now...

I broke off one bolt on the rear diff u-joint yoke.  Yoke came off okay and I managed to drill and pick
out most of it (just couldn't get an extractor to turn it out), but there's still some left that I think I
should be able to chase out if I can find the right tap.  Since I can't spot my thread gauge, can anyone
tell me what the size & thread are?  And where's the best place for taps around town these days?  I've
always like dealing with Triad, but something down south would be nice so I don't have to go way the
hell up there.

Use one of the bolts to figure out the threads, I work at Acklands and we have tons of taps, just message me what you need
