Muffler clamps.  There are some that fit perfectly and work great!

Greetings, all

I'm "improving" my elevation rotor setup, and I'm wondering what others 
are using to secure the cross-boom inside the elevation rotor.

I've been using stainless hose clamps, and they work kinda-sorta OK, but 
have a tendency to slip.  I'd really like to get either some proper size 
u-bolts, or the part numbers from the clamps Yaesu supplies with the rotor.

They appear to be 54mm / 2-1/8" inside-the-legs, and I'm coming up blank 
on searching for some.

There are no part numbers for the clamps in the manuals I have for the 

I have FOUR elevation rotors, and NO clamps!

Seems like the clamps always get lost when people take these apart to sell.
