problem solved - i sold the RD with the FD and shifters and two DT clamps.
I'm going to switch the Schwinn over to SunTour drive train parts. Having the Shimano RD and Simplex FD/shifters and Dia Comp brakes & Shimano levers.... all the mismatched parts was always distracting me while I was riding. I didn't think I had OCD.
hopefully I'll forget I have Malliard hubs.... dang it!!
ciao
sunnier days
