Grayhill encoders are pretty good encounters that are easy to mount and use.

The SS output shaft hole on the end of the axle (where the wheel goes) is tapped. The hole on the other side (where the slip ring goes) is 1/4" but is not tapped.
+1 on the Greyhill encoder. We put the greyhill encoder into the untapped 1/4" hole, connected the wire and then ziptied the wire to the gearbox plate close to the output shaft bearing.
