Well, It shouldn't need to be sealed at the disco anymore becuase its just the shaft now. I thought about sealing it there but the one piece axle I think it a different diameter than the 2 piece, not 100% sure but maybe someone else can shed some light on the 1/2 peice diameter? Never got a chance to get a caliper today.
Napa # 11800 or 11777
One seal OD is just slightly larger than the other... wonder if I should go with the larger one and try and make it fit that way its more snug?

I'm sure it's a type of plastic and it's a bushing. http://www.4wheelparts.com/Dana-Spic..._pn=D%2FS43342

Called Napa, they don't even have the smaller one in state, said it wouldn't get here till monday or tuesday next week. So I'm gonna give the larger one a try on Thursday, if no luck then I'll order the smaller one.

I don't recall seeing a seal seat on the passenger side of the carrier in my vac disco D30 which is why I was working on the assumption that the seal would be located at the disco orifice. In my D30, the axle tube is welded to the pumpkin and there is no way to insert a seal there, it's not machined to accept a seal... because the seal goes in the disco orifice. The seal I linked is specifically designed to fit in there and accommodate the smaller, 1-piece axle diameter. At least that's my understanding.
The locking pinion that is moved by the disconnect fork (to couple the primary and intermediate axle shaft) is machined steel, not plastic or aluminum. JBimmolate has found your plastic pieces.

arghhh!!! 
so frustrating lol. Waking up first thing in the morning, gonna get a little 6" electric caliper and measure my damn axle and housing and everything I can around that area. I wanna make sure I only have to replace this fu<k3r once! BEAST MODE ENGAGED
In the write-up you linked they show an inner seal at the diff on the passenger side. Maybe that's the case with YJ Disco D30s but not on my XJ. The disco has to be lubricated by diff fluid and if there were a seal there it would prevent the diff fluid from reaching the disco so they moved the seal outboard. I've found several sources that back this up, including post #6 in this discussion of disco-non-disco conversion.

freegdr posted a video from bleepinjeep that shows using my same setup using a seal in diff instead of at the housing. After looking at his comments he said to call rustys because he couldn't remember the part # so I searched on their site and found this...
http://www.rustysoffroad.com/rustys-...-seal-kit.html
I wonder if this is the same as the link you had posted F1Addict on page 1, only this one has the block off plate?
Edit: Called Rustys, lady on the phone was super nice, said she was going to go to the warehouse and pull the part to get the diameter specs and would call me back in like 30 minutes, got the call 10minutes later and she said that the shipping guys won't open it because it comes as a kit and they are individually packaged inside of a packaged box. She did say I could order it though and if it doesn't work I can return it for store credit. Although I'm still wondering if the link on page 1 is the same part... I do not NEED the block off plate because the previous owner must have taken an angle grinder to the vac disoc fork, although the one with the back off plate is only $7 more... you guys think I should order it from Rustys?

The question is whether or not there is a machined seal perch on the passenger side of a vacuum disconnect differential. Obviously, there is one at the disco orifice. I don't recall seeing one at the diff on the passenger side but maybe I just missed it? It certainly looks like there is in the BleepinJeep video freegdr posted. Did they machine TWO seal perches even though only one would be used? I don't know, you'll have to look.

Couldn't get a decent quality pic, too close for my phone. But I rewatched BleepinJeeps video and mine looks just like his, so as of right now looks like the Rustys kit is going to be the best bet. Ordered it today so hopefully it will be in early next week.
