These D washers are used under the nuts that hold the brake drums on for the AC Ace and Aceca cars, maybe Greyhound also.  These are commonly bent, rusted, or missing so we made up a bunch during some AC restorations here in the shop.  1.5" OD, .420" ID, and a beefy .125" thick with a plated black zinc finish.  Price is for a set of 12, enough for two drums. If you have a car with drums all around just order two sets. 

Ebay is also now collecting duty in advance on all international shipments.  The duty will vary according to country and will be based on the full selling price.  This is not under our control, so please be aware!
