The Granadas were made the same years as the Mustang II's which were based on the Pinto platform. The two lines don't share any interchangeable parts that I know of.
However, a lot of the Granada chassis is very similar to the 70 and older Mustangs. Hence the fact that we are able to use their rearends and brakes. It might be possible to retrofit the column but I think you'd be breaking new ground as I've yet to hear of anyone else doing such a thing. Might be worth investigating though.
