Pony door help....

[Mustanglike]

I'm trying to fit the deluxe/pony door panels on a '65 for the first time.... it appears that I need to drill holes in the door for the door cup brackets?

Is there an easy way to figure out where to place the holes on the door?

Is there a templet or does someone have a door apart that they can snap a picture of to help me?

THANKS... again!
