with a 22 tooth inner chain ring and a 28 tooth inner cog, I'd have a 20.4 gear inch low gear, without having to switch out any other parts.
Much easier to change out the freewheel. Go to Sheldon Brown's site and find the Cassette and Freewheel area. You should still be able to get a 6-speed 13-34. If you get desperate, I suppose I could let you have one of my spares if you pay the shipping.
