you don't need shocks, the capsules are internally shockmounted. Neumann sells a mount that screws into the base of the mic and then has an arm that attaches to a regular mic mount. I think they're like $200/pr from Neumann, Damon used them...
if you really want shocks I used the rode ld mounts... they are similiar to the adk mounts but fit a bit better
if I still had my u89s I would use the neumann mic mounts though, much smaller and easier to deal with
Are you sure about this Tim? I've never read or heard anything about this. I know about the base attachment, but never considered it. In hindsight, I think I Dan Estrin actually used the base attachments. Can anybody elaborate on this?
Anybody have the u89i pics from Big Cypress. I had one that I'm trying to find right now.

yeah, i used the swivel mounts for the u89's and I thought they were great. I spoke with doug oade and someone at neumann before I bought them and both confirmed that the capsules are internally shockmounted and do not require the big basket mounts unless you are going to be in a really unstable location (doug's example was micing a drum kit). running the swivel mounts with an AKG t-bar is ideal in some ways. the bar itself is 20 cm (8 in) on center to the screws and the swivel mounts are 5 cm (2in). so with the bar fully extended and the swivel mounts perpendicular to the bar, you get 20cm of separation for DIN and with the swivel mounts flared out to the side, you get 30 cm of separation for NOS.
i picked mine up individually on ebay for a total of about $1700 ($925 for 1 and $800 for the second)...sent them to neumann to be cleaned and checked for $175. i thought it was a great value. 5 patterns and great sound for $2k, try doing that with SD mics.
EDIT: the biggest detraction for the swivel mounts is that they do not swivel in the right way to use them with a shure vert bar to get a coincident setup for xy, blumlein or M/S. however, i think the BCostigan mod vert bar takes care of this problem for you, but unfortunately it had not been invented when i owned the u89's.
second edit:
from neumann's description:
"The capsule it is elastically mounted to avoid any structure borne noise that could interfere with its operation."
