Is there an accepted method for determining the size of the glass based on the hole of the specific window which takes in consideration the thickness of the rubber seal for each widow? Obviously the vent windows are easy, after that it get more complicated.

Pat S--I just bought a complete set of glass for a 33 Master 4 door(12 pieces) from "The Filling Station" http://www.fillingstation.com toll free 1-800-841-6622 They have access to patterns for just about any Chevrolet, you can also just buy the piece of glass that you need.
