Did they ever produce a slant 6 4 speed with a console in 1966?

That error was mine—Windsor started building cars for the US market in the '66 model year, but US and Canadian models were still separate (111" wheelbase A-bodies built and badged as Dodge Darts for the US market, with the options Chrysler Corp allowed…built and badged as Valiants for the Canadian market, with the options Chrysler Canada allowed).
