Hi Crabfu, thanks for the pictures on the Le Mans racer This is exactly what Roly was describing in his picture too. A simple L shaped bar that would be connected to the steering rig of the original steering. Mine should be coming today and when it does I'll have some pictures of it on here. I am also reciving a 2 piston double acting steam engines that a guy is machining for me. The cylinder block is ½” x 1-1/2” x 1-1/2” aluminum, and the base plate is 1/8” x 1-1/2” x 2” aluminum. It should be self starting and I will try to Mount it to my roadster.
