door glass clips???

Man, talk about timely; I will be hitting this job sometime next month (I hope). What size where those washers? You wouldn't have a part number for them would you? If they have a lip on them they must have been some type of specialized washers.
I think that hole in the glass is 1/2" if I remember correctly. Did you use a 1/2" bolt or a smaller bolt with a sleeve over it?
Many thanks,
C
