I have an 1811 with an aluminum rear and I put a sleeve hitch on it with no problems. I bought the two big bolts that fit into the two holes at the top sides of the frame rail from one of our sponsors and the hitch on ebay. You just have to make sure that you buy the correct arm that goes to the hydraulic actuator under the tranny cover. On some models the arm comes with a bushing for the hole and other arms come with small blocks drilled and tapped for the installation. I also went with Xtreme motor works's lower bracket for the hitch because it wraps around the rear end and has two holes for bolts that are for the axles and thus gives the aluminum rear a little more support for hard pulling.
