LOL! I'm everywhere!
I know there is a good joke in here somewhere, but I can't find it in this heat.
That said, if you didn't already buy the Vintage Air system, I second the recommendation to look into the Old Air Products setup.
If you do have the Vintage Air unit already, I vaguely recall their instructions having a full size drill template that you could hold up and see which (if any) holes line up.
