Thanks!
You probably have a 120 mm spacing in the rear which will more or less restrict you to a 5 speed freewheel (they make 6 speed ultra f'wheels that will fit but they are expensive). It's not a big deal to spread the frame to 126 but you'll have to redish the wheel. Personally I'd stick to 5 and keep this easy. IRD sells 5 speed freewheels: Defiant Freewheels, 7, 6, and 5 speeds

Or you can get one from one of the bike hoarders, I mean collectors, on this site.

Cool bike and worth fixing up.
