Report Brake Drums Part Number in 1965-83 Avanti Posted March 5, 2008 Jeff- I think the easiest way to get brake drums is to call Nostalgic Motors (800-Avanti-X) and order them. I do not think there is an "off the shelf" replacement, at least I was never able to find one. I know of some other brake drums that will work but they require machining, spacers, etc. New ones are expensive, but you'll probably never have to replace them again! The shoes are easier to find; they're a Wagner #228 which was used in many other applications.
