    OK... I think I will be installing the drivetrain this weekend. I have been looking over all my parts, and I keep coming back to this cross member:

    I don't see how the trans or transfer case could mount to this piece. If anyone has any suggestions, or if someone could take a good picture of their NP205 mounted, that would be excellent. I can't wait to hear the big block turn over - or to pay for it's gas!!!

    The adapter that goes between the tranny and t-case has bolt on the bottom of it with bushings that bolt to the two middle holes on the crossmember. So the tranny nor t-case actually bolt to the crossmeber, just the adapter between the two.

    The 205 adapter bolts up to the two large holes in the center of the crossmember. The bushings fill the large holes and a plate & bolt go in from underneath. Don't have any pics though.

    The T-case doesn't mount to the crossmember, the adaptor should have 'feet' on the bottom that bolt to the crossmember.

    That looks exactly like my 205 crossmember...

    Glad to hear that this is the correct Cross Member, but I don't know now if I have the "adapter" that goes between the trans and transfer case. I only have a solid sleeve that joins the output and input shafts of the two. Other than that, it looks like a direct bolt-on type of deal.

    Of course, neither of my manuals have anything about the 205. So if anyone could come up with a pic, I would be eternally grateful. Thanks!

    That is the drive sleeve and it goes inside the adaptor...the adaptor is roughly 6" or so long and has a mounting face on either end as well as a press in seal on the T-case side. Send ThatK30Guy a pm and see if he has any adaptors for sale. They're hard to find...

    Great Pics! I do have the piece that hhas the foot on it, or the 'T' shaped thing. Its bolted to the xfer case right now.

    You can see it in the pic above. I hope I have everything... What kinda truck can I tell the parts house this xfer case came from in order to get replacement seals and stuff?

    I have already gone to the dealer, and ordered the shifter knob, the rubber boot thing to seal to the floor, and the retainer ring that bolts to the floor for the boot. Almost ready to go!

    Finally, how many rubber mounts should I have between the xfer case / Trans and the cross member? Thx.

    T-case is upside down in the picture. You need two mounts (the top is u-shaped and the bottom is a rubber pad). There are two sleeves that goes inside the mount over the bolt. Your best bet is to get the Energy Suspension mounts. They come with everything, sans bolts, and are urethane to boot. Seals, Blumenthals here in OKC has a seal kit for the 205 about $25, you may have to go to a transmission supply shop to get them (4xheaven has them also). Looks like a slip shaft 205, tell them it's from a 1980 Blazer (full size, they'll ask and also 4 wheel drive), part time unit. Do you have the bolt that holds the shifter to the adaptor? I have the small linkage that hooks up to the shifter if you need it.

    If your T-case is a fixed yoke, it's probably a 70-79. I think the 70-72 used a bushing on the adapter, and 73 up used a bearing ( not 100% sure how to tell the difference). There are two rubber bushings that go from the tcase adapter feet to the x-member. You can pick up urathane bushings for about $45 bucks if you dont have the stock ones.
