Where did you buy your glass from by the way if you dont mind me asking? Im just getting some quotes at the moment. That seems like a good price considering the profile etc.
Its a small independent shop that's near to where I live, they don't actually do the work in shop they send it out to another company to do all the polishing and cutting.
You have to shop around for the best prices, I was quoted double what I paid in the end.
With regards to the CP's I wouldn't go down the same route I have been using as its very time consuming having to cut the middle section of the end pieces out to fit them.
My newer design has the rear section of the cp bolted to the end piece, this way should you ever need to replace it you won't end up with fatigued screw holes in both pieces.
Simple four bolt holes in both pieces and a 2" hole to feed the cp wires through.
The top of the CP will be held in place with four chrome counter sunk allan screws to keep it looking nice and clean and its easy to quickly undo those if you have to change the joystick etc.
