Cam Drive Pins
The Danny Bee hub has the pins exactly 180* opposite. That's the way we like to do them, then all your cam gears or Danny Bee drive hubs will fit all your cams and vice-versa, any of your cams can fit your existing top gear or hub. Therefore I respectfully disagree with the idea of just drilling a second hole through both the gear and the cam at the same time. Odds are you will be "off" one way or another and not be exactly 180* opposite. Therefore they become "dedicated" to each other.
In addition to Jet Boat Bob and the other shops mentioned above, Wayne James and David Willingham can both do it. Those three guys have fixtures. Just UPS your cam and gear/hub to any of those guys.
Hope this helps,
