Door window crank handle washer

Guys does this even fit a 280z?

how do u insert? If u insert with the beveled edge towards the door handle it does leave a bit of space from where u can see the pin. Is this the right way? Other way it just flushes with the handle and u cannot see the pin.

originally I did not had these and got the handles off easily as there was more space. Just wondering if anyone used these and after that it is easy to unpin the handle again.
