I have a Totem manual, but for some reason, it does not include any specs/diagrams/part numbers for parts on the underside of the playfield (e.g., pop bumpers, etc.). I need to replace a few items, but don't know their part numbers. Is there someplace else I should look? I'm specifically looking for the part number for the plunger in the pop bumper. Perhaps this is a generic part, but really don't want to order the wrong one.

Thanks.

thanks!
