    Need help figuring out crossmember attachment to the D18.
    Precisely the rubber donut cushion attachment.
    I may be missing parts or have the incorrect parts in my basket case of junk.
    I have looked in my service manuals but cannot find any exploded diagrams or photos of crossmember to trans & tcase.

    Here’s some pics from my parts manual that might be relevant?

    Those are all D20 diagrams.
    The f134 with t90 and d18 is a simple arrangement that goes through the hole I the crossmember with the sholder bolt. The d18 ear is on top of the large doughnut is open side down on the crossmember then the small doughnut has the small step locking it's position in the crossmember the bolt goes up from the bottom. If you don't have a t90 crossmember you may not have the hole.

    Here's the T-90 style parts. I believe the "snubber" goes below the crossframe and "insulator" goes above it. But I don't have one here to look at.

    Here's a few pictures from @compostwerks project showing the metal cup from the insulator and how it is on the frame. You can see that and the rubber of the insulator in my picture above. Yes The snubbed is on the underside. You don't need to torque it all down very tight it is a lock nut.

    Note that the bolt is a shoulder bolt. This is required so you don’t over-tighten the rubber parts.
