35 Wiper Shaft Grommet Cover and Nut ?

[Trelpdx]

Guys,

Just rebuilt my wiper motor and getting ready to put on the car for the first time. I purchased a new rubber grommet and I have what appears to be a gromment cover but I'm not sure it is correct. It is quite a bit bigger in diameter than the grommet. I don't know what the final assembly should look like. Can anyone send a close up picture? Also, the chrome nut that I have is a skinny nut. Is that correct, or should I get the regular size chrome nut?

Thanks much,

Peder
