Come on Arfon, you have a full CNC shop at your disposal, don't you? I 3d printed my rollbar mount. Ugly, but functional: http://www.thingiverse.com/thing:857676

I do have the workshop available but right now we are at full tilt with students and final year projects it's bloody chaos right now, it's that bad that in order to do any work on the car I'm having to stay late at night, was here til eight pm Monday and Tuesday.
