And before anyone whips out their handy tap and die set to make one, the
5/8" is not a normal standard thread. It's 5/8 X 27 threads per inch,
which is a very tough tap and die to get. Special order item, took me
nearly a year waiting for mine, though I think the supplier has them in
stock now. Here's where I got them:

Really nice to be able to make custom parts. I usually use aluminum for
the threaded parts I make. easy on the taps and dies.
To make it worse, most standard threading feed settings on lathes don't
include 27 tpi.
I know that Crown's mount adapter for the SASS has the threads. It has
3/8" in one end and 1/4" in the other, with the correct 5/8" on the
outside. Part number is D7092-6. Called a Adapter (Swivel Clamp to Hand
Grip), retail $16.60 or dealer $8.30 last I heard. It's machined brass.
For those lovers of exotica, there is also a 7/8 X 27 thread used in
some mic stands. Much rarer, I've never seen that.
