I dismantled This dyer again with the intent of changing out the solenoid coils and/or the gas valve .These coils are a one piece type as compared to most older units which are 2 separate . They are held in place on top of the gas valve with several screws that are different in that they appear to be a Torx but have a small internal pilot stem. My Torx tools will not fit and am asking anyone with knowledge of these screws of where to get this kind of tool ? Help !!!
