[91A-77B]

Thanks for the comparison photo. You've solved another problem I didn't bring up, the need for an offset clutch arm. Mine is the 48, as used in 35-38; I need the offset (91-A).
Back to the problem; if I drill a hole further down the shaft and attach the clevis there, will the arm have a longer back & forth movement? Need an engineer of math guy to figure that one for me.
