Inspection marks in engine bay

The same person made both marks. Looks like they may have started another one over near the wiper motor, but didn't finish it. I'd restore the engine compartment, and recreate the marks. My 70 Challenger A66 car is all numbers matching, and has a few left that I will put back, and one I will not disturb. The few I will put back are in the engine compartment, and the one I won't mess with is the "ROCK" signature on the rear drivers side inner wheel well in the interior.
