I'm trying to help a mechanically semi-illiterate friend install the dzus fastners on his car. And I'm doing it by phone, long distance. What I don't remember is should the piece (shaped like a hat) that extends in the bonnet flatten when the washer is pushed up to contact the groove in the dzus? I think so but it's been a couple of years since I installed mine and that's way too long for me to remember anything.
