Parts book calls for four 80421-000 , 1.75" diam. pulleys. These have .25" center holes. This fits fine in the upper wing location mounted on AN4-14 bolts (wood spar wing). However, the fuselage brackets are sized for AN3-7 bolts. The parts book calls for all AN3-7 bolts. Anyone else found this situation ? I'm tempted to bush the fuselage pulleys down to fit the AN3 bolt diam.
