For anyone who’s curious, this is what the original distributor cap looked like when your ’67 pride and joy left the showroom floor.
I just purchased one of these NOS. The correct part number is 111-905-207 C. They might be a bit hard to find but keep looking. Wolfsburg West also has a good read on Volkswagen Distributor Versions.
If by chance you’re an old German VW mechanic with a stash of these sitting in a barn somewhere, please contact.
