where to purchase template to drill flywheel

I'd like to see the picture if possible as I am making what I call a 'drilling jig' to do this job.

Also, there's the question of the angle of the drill tip. I've had it pointed out to me that nobody seems to know whether it should be a 118° or 135° included angle, both are 'standard' for these drills. Any information would be greatly appreciated.
