Yes, my '66 105.02 GT has a plastic canister. I think that metal brake fluid canisters were last used with the 101 series.At least starting in 67, they used the wide-mouthed plastic BF canister. I believe they go back to 65's as well.
More likely a beer can!If TimBob is BubbaBoy and JimmyJoe's friend....he'd use a soup can.
