Some has asked me to post pics of a failed experiment I did trying to mate a GS120 to a Prodelin 1.2 commercial dish. This did NOT work as the dish and mount were still way too heavy to work. I made the frame out of 1X1 steel angle and the bracket is a foot mount from a directv slimline dish, with a conduit clamp assembly to adjust elevation. This setup MAY work well with a large motor that has the guts to pull the heavy dishes up the hill.
