You cannot unfortunately since screws are on different sides of head between the 2 36t on selection switch side and 80t on square drive end atleast on the 3/8 size they are
I had the 36 tooth variant. It was picky about dirt. The bottom plate fit kind of loosley. It had to be cleaned often or it slipped. It had a few replacement kits in it. Must be why the screws go through bottom plate into the head on the f80. That must keep the bottom tighter and the dirt out. So far my f80 is holding up good.
