what is correct nylon washer for H4 rim screw

[speedster911]

cannot locate a part number for the small nylon/plastic washer for the H4 headlight mounting screw. Can someone provide the part number or a source of what you have used. Thanks

Try these p/n's, first one is the mounting screw that includes a washer, the other is the washer used for the trim ring. Don't see an individual part number for the mounting screw nylon piece.
