I got a Park Tool FR-1 thinking it was what I needed, but it does not fit either of the 2 10-speeds I'm working on (nothing special, just a Murray & a Huffy both from 1982). The Murray's rear hub has 9 splines and is approx. 1-1/4" dia. and the Huffy's hub has 12 splines and is approx. 3/4" dia. Does anyone have any idea what freewheel tools I need?
