1968 Polara Electric window upgrade

Good Morning fellow C-body Lovers. I'm restoring a 1968 Polara and I'm upgrading to Electric Windows. The Motors and the Actuators off Newport fit the Doors perfectly mounting holes were already there! There is no knockouts in the Bulkhead or Doors for the Wiring Harness. I would like to get some measurements from some fellow C-body brothers who has an Electric Window setup before I break out the hole saw! Thanks!
