ENGINE COVER STRIKER

This "little triangle looking thing" is attached to a threaded insert in the bottom of the engine cover. Sometimes, inexperienced persons attempting to open the DeLorean's engine compartment without first releasing the latch (pulling the handle near the bottom corner of the rear window on the driver's side inside the car) can literally pull this engine cover striker and the insert out of the engine cover. Then they get lost. The parts, not the person - they're usually a relative and they tend to hang around. Fortunately, the parts are inexpensive so you won't have to disown them.
