What's with that intermediate gear countershaft sticking out of the transfer case? Assuming that groove is for the o-ring, I've never seen one with a small nub for the locking tab like that before.

The counter shaft from this rebuild kit has two o-rings instead of one in the original shaft. The smaller bit on the end stays outside so it doesn't matter about the operation of the case. It is also of dimensions that it still picks up the locking plate

Looking at that rearmost boss where you have no clearance with the d20 transfer case front cover. There were some variations in the castings for the t19 cases, or at least that's been my experience. My first go-round with a t19/d20 was a boss in this same area (May have been more forward) and I had to grind it down so the d20 would clear the side of the t19 case. Oh, it's important to note that the t19 case was from a 2wd truck and I had to drill the missing holes on the rear of the case so that rear bearing t/c adaptor would mate up. It wasn't a situation of bad clocking, either. The case simply had some extra bumps on its side.

Thanks for the compliment. I solve problems for a living. I am a physicist with an honest to gosh phd (piled higher and deeper). I design experimental hardware for a living.

Got my first Scout in 1986, when I was a kid long island boys wished for four wheelers. Wrenching my scouts is relaxing. I have restored a 1960 vw bus with my daughter.
Bill hamilton's got me beat for resourcefulness but I try to keep up a little

I asked an expert from another vendor and he said that they have not seen much variations in t19 bodies. In this case since it is a wide ratio it almost certainly was in a Scout.
It had a Dana 20 mated to it with a linkage I never saw before. I took it off so long ago and it is back in the us I don't remember what it looked like. I always assumed that the tranny and tcase were out of a Jeep. I didn't even realize that it was a t19 until I started rebuilding it!
Since the bell housing on it matches mine it would seem that it was n a Scout. However, the nose piece was significantly shorter.
Hoping somebody out there has more to add.

I've run into this problem several times in the past. As Mark mentioned the 2wd t19 case is different from a 4wd t19. Not much difference but enough that you have to do what Mark has already mentioned. As for the Dana 20 I have seen different front bearing retainers(that incorporates the shifter tower) that have less material on them in that region in question for the extra clearance needed on a t19. My guess would be that the transfer case harry is using is from an earlier model Scout II that has more material around the shifter.

Jeff,
thanks for the confirmation. It's been over twenty years since I did that and the memories are drifting back, so for what it's worth:
a vendor sold me a t19 from a Scout that had hidden cracks. I picked up a t19 from a 2wd at a pic'n'pul for cheap. The cases were otherwise identical except that on the passenger's side of the case, there was a boss that for some other type of application would have been tapped to mount a bracket of some kind. The front bearing retainer on the d20 would clearly not clear this boss, so I ground it down almost flush with the case and got the clearance I needed. Also, there was another boss that cleared everything but had a tapped hole - so I retapped for a pipe plug and plugged it. So there clearly are Variations in the same basic case, depending upon final application. Jeff pointed out variations in the d20 front bearing retainers. So one could conceivably have the interplay of two "variations" at work that could momentarily stop one in their tracks, until they pull out the grinder!
Regarding drilling/tapping a 2wd case for a 4wd application. Some of the holes that hold the 2wd bearing retainer in place line up with their 4wd cousin. So you put a bearing and snap ring in place, and bolt up the 4wd adaptor with those bolts that line up. Accurately center punch the needed holes, drill and tap, and then plug the 2wd holes that don't line up. I put gobs of miles on that case and pulled a trailer through off-roading trips, so one shouldn't shy away from adapting a 2wd case if need be.
