MFI Microswitch screw and hardware
Since I have finally decided to fix my excessive fuel consumption(12mpg at $3.60 a gallon is a big motivation!) , it dawned on me that my microswitch should be checked. Lo and behold, I am completely missing the microswitch screw/locknut/whatever else is supposed to be there on the throttle mechanism!
Does anyone know the exact sizes of these parts offhand? (or willing to measure theirs  ) I have an excellent hardware source nearby, but I need to know the pitch and length of the screw, and also a list and/or pictures of the other hardware.

The screw and nut are both M5, the screw is a cheese head. I don't know the length offhand, it's about half an inch (OK, 12.7mm long) but you could use a longer one and lock it with the nut, won't hurt anything. Use some red loctite once you get it set so it doesn't vibrate loose (which is why it's missing in the first place). The end of the screw has had the threads ground off to make a nice smooth mating surface for the plunger of the switch.
Picture is in PET.
