Conversation Between daveengelson and BruceWayne

After taking the door panel off, I see where the pre-owner covered the holes. I think I need the measurement from the front edge of the door to where the slot would start. From there I could create a small hole and then be able to look into the door panel to see where I cut out the rest of the hole. it appears to be an inch or 2. Any help on this measurement would be greatly appreciated!
