Going to have a bash at this..!!

[mikemph]

I am pretty sure I have a spare set of plates in 6mm already cnc plasma cut.

They mad need a buzz over with a angry grinder, just to take the suface rust off, and the holes might (unlikely) need a drill running through to make them perfect but they are yours for a few beer tokens.

I think I also have to front wishbone plates again 6mm plate but with extra few cut outs probably lighter than the 5mm ones lol
