Okay I found them. I am after if these you have them of course:
S_UN_Rock_SM_ArchCliff
S_UN_Rock_SM_Blackcliffs_wall01
S_UN_Rock_SM_Blackcliffs_wall02
S_UN_Rock_SM_Blackspire01
S_UN_Rock_SM_Blackspire03
If you have those I would be so more than grateful if you've moved them over to UnrealEd3.0 as .usx
You'll be Credited in the Occupant17 Mod of course.
I am not that interested in their Materials/Textures but I expect they come along for the ride

I have taken a few UT3 Materials/Textures before because some are great but I have no idea how to grab the StaticMeshes.
