James, if you have an adapter so you can use low shank attachments, then you should be able to use the Kenmore one I posted. (Or the Greist Designer in the "Low Lift" model). The one with the Singer name on it is for Slant machines.
Where did you get the adapter for you machine? I don't think I've seen one of them and it would be neat to have - since I collect attachments and also have a Kenmore high shank machine. I bought mine because I've got a thing for chainstitch machines - I have no idea why, but convertable machines fascinate me.
