Which freewheel remover tool to use on vintage Columbia bike? I picked up what looks to be a late 80's Columbia 'USA Racing' Women's city bike on Craigslist recently. It needs a new 5 speed freewheel, but I can't seem to figure out which remover tool to use.

The freewheel center has 12 slots, and is 22-23mm in diameter (best guess is 22.25mm). I happen to have the FR-1.2 and FR-5 and both don't fit (too big).

Also, can anyone suggest a decent freewheel for this bike for around $15? Thanks!
Take it to your favorite IBD- they can explain and illustrate much better. They might even show you how to do a destructive freewheel removal! Since bikes age in "dog years", and the correct tool to remove it (thick -boss Shimano) hasn't been made since the '90's), your shop may not have the correct tool unless they have been around for a while. IBD freewheel removal should be about $5 or so plus freewheel, if you bring just the wheel.
