Hi I know this is a Nova site but we have a 1966 Acadian Canso Sport Deluxe L79 (327ci/350hp) which is built on the 66 Nova platform and only sold in Canada. It is a factory 4-speed car with a 12 bolt posi rear end. GM of Canada documentation says only 85 of these cars were built in 1966. We also own two 1965 Acadian Beaumonts Sport Deluxes built on the Chevelle platform. These are both L79 cars and are Documented by GM of Canada as being only 23 produced with the L79 option in 1965. :D
