WE use it for timing the engine.

The Canadian military trucks we restore have a semi cab-over-design and servicing the engine with out removing extensive cab sheet metal has forced us to be creative.
To complicate things the trucks are right hand drive with the clutch on the same side as the timing mark.

Solution is to find the TDC and the best timing for the engine while the cab is not yet installed. Then remove the inspection plate, mark the clutch assembly with a cold chisel and a dab of yellow paint. Next time you need to time the engine it is an easy step to remove the COE engine cover, remove the inspection plate and stretch a piece of wire between the two screws... then use your timing light. You will need an assistant to adjust the dizzy for you.

Phil W. of N. H. came up with that solution, I am only the messenger.
