John, I have replaced the wheel on my 1993 C36 with the folding wheel. Only problem I had with my Autohelm 4000 was with the plastic U clamps. Each had to be enlarged with a Dremmel tool and a large diameter, 3/4", 1/8 " thick neoprene fawcet washer added between the U clamps and the Autohelm plate. Without this change, I had problems with the Autohelm coming apart,
