I need the part number for the clutch pedal safety switch on an Allis Chalmers 7080 Diesel Tractor.

Hi,
There should be a black on white or silver tag with a seven digit number under the seat area or under the hood that is necessary to correctly answer your question.
Peace,
Clarke

Could not find your specific part, but this site gives you a number to track it down,

Possibly its part of a greater assembly.
