We used to trim the fins from the back of the slipper during the installation - Rene, being the thorough guy he is, likely mentioned it somewhere in the build. This was intentional to minimize overhang, but also to allow ample clearance to the mount(dimensions are driven by the Gorilla chassis), which is very close(mount is machined to fit around the input shaft as well, while allowing room for the adjustment wrench). There should be enough room on the shaft to simply slide it a little to allow clearance, but grinding the fins was part of the plan from the onset.
