New bridge for Stagg EUB

[ag42]

Has anyone every put a different bridge on a Stagg EDB EUB, or managed to get hold of original bridges? I ask 'cos I have a Fishman Full Circle pickup I want to try out, which screws in perfectly to the bottom part of the bridge (5/16-18 threading, just in case you wanted to know!), but the top part of the Full Circle isn't threaded and the top part of the bridge is, so it'll move around. I want to get hold of another top part that I can fill with wood somehow and re-drill, and keep my original just in case I mess things up. Or, put a different bridge on that I could drill from scratch, but so far I've found no-one who's put a different bridge on.

Any ideas anyone?
