there is a hoop part that bolts to the motor in the front look for the 2 holes one on each side. I may have one if you need. getting hard to find. cable and pulley or push pull will work on it.
They show up on ebay once in awhile, probably more often than the Mk20. The steering swivel to connect the cables to the hoop don’t show up hardly ever. Only seen one. A inventive person could probably figure out a work around
