We did that in the back parking lot of The Galaxy Diner. Jerry Thayer's 85GT.
Since then I've changed my method a little. Using my fingers as I did as a wedge to keep the dew wipe tool engaged with the screws made them very sore. I began using the little wooden wedges that are used for setting doors and windows in the home. Push it down between the door and tool to keep the tool engaged with the screw.
You can see the magnetic pickup tool placed underneath the screw in the event it falls out. Apparently, that's not a common screw that can be found in hardware stores, and when it falls into the door, it tends to find that very thin crack to fall into. I use a little spec of the black butyl windshield setting tap on the screwdriver and dew wipe tool to help prevent losing the screws. You can briefly see the box when I get a piece for the screwdriver.
Don explains how he takes a sharp tool and splits the center screw holes and leaves the screws in place. Then he snips the new wipes to make them slotted on the two center holes.
I don't know if I mentioned it in the video, but the rubber water seals on each end that are removed at the beginning have little plastic washers underneath the screws. Be sure to save those else the screws will pull through the rubber after they are reinstalled.
