Please , while we are on the subject of Canadian cars, my 31 Coupe here in Michigan was the recipient of many parts from a Canadian doner that dad and I towed across the bridge back in 1963. The engine is CA05513. As a way of the honoring the cars heritage, the rear window garnish molding is secured with the square head screws.
Can we date the engine from that serial number?
