My 81 is wearing bigger drums from an 85 Audi 4KS because they were 
newer, cleaner, and not rusty at the time.  You need the backing plate 
so you get the stubs, too.

Sidenote:
I must have one or two of those AC vacuum valves somewhere but I 
couldn't find them in my first foray to Partsville, Basement.  What do 
they look like again?  Are they white?
