I can't do any international orders unless you are willing to bribe me to make a personal trip to the Post Office, sorry!
To answer your question, yes, the aluminum threads surprisingly well. That is how *I* have chose to use the 7/64 holes. 3mm machine screws or self-tap (traxxas style) work well. The self-tap just go on a lot more quickly. If this method failed to work for some reason, you could always use a locknut.
As the mounts take up the shock mounting locations, you can see in the above picture where I relocated the shock mount ball. Look between the servomount mounting screws on the leftside.
I used an HS-85, and I would expect any mini-servo to fit in there fine. I bought a servosaver off of Ebay that worked great. Its described as a "GPM servosaver" but it is some cheap knockoff I think.
4-40 rods from the hardware store, RPM rodends, and some ballends I had laying around.
