Yes get the rapid adapter
with the additional 3/8 -> 5/8 adapter and it will fit the AKG KM235 stereo bar.
Here is a photo of what I run top end for near coincident - the whole thing broken down:
Rapid Adapter - terminates in 3/8 male thread.
3/8 -> 5/8 adapter - terminates in 5/8 male thread
KM235 - accepts 5/8 male thread
It is the one on micsupply.com that has the photo. $17
