Go to your FLAPS (friendly local auto parts store). Buy a generic spacer made
for something like a Camaro with oval holes. They will work jus as well. Not
as pretty but shouldn't cost you more than about $10.

Vanagon rotors are too heavy even after you cut them down. Besides cutting
them down will probably cost you more than getting the machine shop to make
nice aluminum ones. Steel and cast iron is harder to machine than aluminum.
