RSST bent centre post replacement?

[Cabbo]

I've gone and bent the centre screw of my RSST (I have no idea how it happened), and now it's making contact with the negative centre tube it sits in. Does anyone know where I can get a replacement? Or if the AC9 screw will work? Or a good way of bending it back straight? Cheers peeps.

It only just occurred to me that I could just put some insulating material between them. But the questions still stand.
