1974 Duster Front Drums

My 1974 Duster has 10" finned front drums. Does anyone know of 10" drums that are not finned that will fit my car. At some point I plan on doing the conversion but that may be some time down the road and I would really like to get rid of those fins, they cause me to use a spacer to mount my wheels and I would like to get rid of the spacer.
