Decided to tackle this project today and wanted to thank everyone who has contributed to this thread. Made a tough job easier.
My 1971 still had what I imagine is the original switch with slot-head screws. Made the top screw all the more challenging.
To pay this thread forward for anyone else with an older F-Body 911 featuring the slotted screw:
- The angle of the drive-bit must be perfectly square with the screw head and the the mini-ratchet won't work (at least wouldn't work for me with the slotted screw).
- A 1/4 in. open ended wrench will easily turn the driver-bit while you use the index-finger of your other hand to push the bit and maintain engagement with the slot-head screw.
- Unless maintaining a concours car, replace the slotted screw with a Phillips head or hex-head M4-.07 10 mm (mini-ratchet worked perfectly for this). Your future self, or the next owner will thank you!
