Does anyone know where you could buy the tool to use to remove the screws that are holding the window regulator and window ventilator parts in on the inside of a 55 2nd series door?? These screws are also used on the inside of the bed panels to hold the rear fenders on (bed fenders screws are bigger though) and door strikers. I have checked with Advance and Auto Zone and they don't carry the tool. What do you call these types of screws??
