Thanks Josh. Looks to be almost perfect but no longer made. Also too thick. I only have 8mm to spare.

There are various sizes at Optcorp, Telescop-express.de and Bintel (I think) and you should be able to get something suitable for your rig

Thanks Charles. Perhaps I should make my own.2 plates with adjusting grub screws may do it. The lacking out is working but I think th eflex is slightly variable with the angle but not by much.
