i've got one akg 235/1 stereo bar missing one 5/8 adapter. If anyone knows where I could find a 5/8 thread that would be most helpful. My company (PSS) is a dealer for AKG and they can't provide this 5/8 thread for me. The B&H link is below for any help. I need the thread what you would ultimately put the shock mount on.

Good luck with your parts search. If you are unable to find just the oem part you are looking for, here's an alternative solution. . .
Pick up an OnStageStands cheapo stereo bar for $9.95 and use one or both of its 5/8'-16 threaded knobs on your AKG bar. A bonus of this solution is you'll end up with a lighter weight stereo bar.
