razer seiren pro xlr accessories?

I know razer hasn't been making this mic for a while, any idea where I can get accessories, like the shock mount? I tried fleabay... I can just about get a blue yeti shock mount to work, but it blocks some of the inputs -- used a dremel to get it to work, but would like the one from razer.

Also, the usb on one of my mics stopped working.. still works on xlr, razer support is not helpful.
Is this a known issue, any fix? (I'd buy a seiren pro for parts if I could even find one)
