Finally got my paddles installed yesterday, and must admit it took me a while to drum up the courage to plunge the exacto knife into the wheel, but now it's done, I've just got to pluck up the courage to disassemble the shifter
A couple of points I will make, first the screws on the airbag on my wheel were definately T30, as I confirmed when I had the horn plate out. Second, when placing the template, it seems odd that it is across the 'knuckle' on the back of the wheel (where the spoke angle changes) which was a bit un-nerving, but once the paddles are fitted, they seem to lie flat.
So for now they just look nice, til I can get enough magnification to do the soldering.......
