Wanted: TU58 DECtape II Drive

I am looking for a rack-mounted TU58 DECtape II drive for my PDP-11/44 project:

TU58 DECtape II Drive

I already have the desktop “TU58-EX changed to TU58-DA” variant; I’m specifically looking for the rack-mounted variant. I expect to need to rebuild the capstan rollers in any TU58 drive I acquire, so an untested or even known-bad rackmount TU58 drive would be fine as long as it’s in good physical condition aside from the capstan rollers.

I also can use tape cartridges for this drive. Blank tapes, tapes with interesting software or data on them, and even a small number of bad tapes with intact housings would be useful.
