Thanks, cal. That's good news about the gear/inches. The bolts on the chainwheel will clear the chainstay if I leave them where they are, but I'll have to put spacers behind the s.s. freewheel to push it outboard and give me a straight chain line. I use 700 x 28 tires.
I should note that the teeth on both my freewheel and crank are steel.
