Screw and backing nut for MFI microswitch

[JTH 36]

Hello all,

I am looking for the screw and backing nut that activates the MFI microswitch in my 74 Carrera. I posted the other day that the car had not been running right and I think I might’ve found the culprit. I’ve looked all over the engine bay and cannot find the screw or the backing nut.

I was hoping someone might be able to tell me where I may find one.

Thanks, Jeff
