1980 k10 cant get tranny and motor back in

[brandenbmx]

I finally got my 383 ready to go in and I cant find the right seal in the np 205. There is a seal that sets right in the 205 input side. There is a splined sleve between the transfercase and the t350 tranny and it has what looks like 2 groves on it and autozone told me that I need 2 seals and that makes sense because of the groves, but the seal doesnt fit that they gave me.
The one was still in the transfercase side the numbers on it are
npg-99484 but this does not cross with anything in the timken catalog.
So my question is where do i find this seal and second does anyone have a pn# for this seal, and are 2 needed? If I had a exploded view of how the tranny and the np205 join I think I could figure it out.......
I have the motor ready to go in this weekend so I am in a kinda cruntch.....
ANYHELP WOULD BE GREAT!!!!

I had this issue too. I took it to Motion Industries they measured it up and hooked me up.

Well I found my seal at car quest.....
That is the least of my worries now. I set the engine and tranny in today "bolted together" went right into the motor mounts, but the transfercase was way off....... and at a angel. So we mated them as close as possible and then jacked the back of the transfer case up and *****BOOM*****
The transfer case mounts, or the case of the transfercase shattered off the mount! So Im pretty much screwed. I just spent like 750 on this thing having it rebuilt last year and I shattered the mounting tab right off the case all because I was in a bind!!!!! so Im Done
