RE: GP 60 Cub Float question
You can fudge a little on the step location, maybe a quarter of an inch behind the c/g. Would that give you enough room for the screws? If not, then you'll need to add more plate area to the fuse in that location, either inside or outside. Either way, make sure the float centerline (longitudinal) is parallel to the fuse centerline, and watch your c/g.
