Howard's sells just the gear (without the shaft) for $76.95.

Inexplicably, Howards uses the same marketing photograph as CAT uses.

The CAT part is $19.95, free shipping.

You have to press the gear off and on, yourself.

I wouldn't be super surprised to learn that not only is the marketing photograph the same, but the part itself just might be the same too.

I should probably buy them both and see.

The MP part used to be manufactured locally in Mt. Clemens MI, but I am not sure about nowadays, and the "made in" sticker might have only referred
to assembly and packaging....for all I know it may have had a $19.95 imported
gear on it all along.
