Yep, you're right Dedman. The one that came with the kit didn't do much for me, found one the net but didn't realise the bracket was curved already.

I knew would need to make a spacer for either one to fit squarely on the angled shape of the body. Decided I didn't want mess with bending the bracket on the tailpiece and possibly ruining it and went with a stop piece instead. Best I could tell the centre block is about 100mm wide, wide enough to drill the post holes.
