David Lambeth still makes them... I think they are modified CRD plates. I just bought one from him and it looks nice. Maybe he could make them a little bit wider, but maybe I am paranoic (I broke my engine casing this spring

)

The TT one looks even better, but it's also more expensive. I got mine for 100 pounds. There is no need to drill any extra holes in the frame.
However, the bashplate won't fit with the Hepco and Becker crashbars for the XT 600, so keep this in mind!
Actually, the crashbars don't fit well with the Acerbis 28L tank also.
Take care,
Adrian
