On my 1956 C600, what size screws and external toothed washers are used for the door inspection plates? Also, what size bolts are used for the transmission cover? I can't seem to find either in my chassis parts and accessories manual.

Thanks for any assistance you can offer.

Can't find a pic of inspection plates to get a basic part number.
