I just removed my back wheel to get it trued up and noticed that a few gears are missing a tooth. Does anyone have suggestions or leads on a 6spd freewheel replacement that won't carry an eBay "vintage" premium?
The freewheel in question is a 13-26 Shimano mf z012. Rear spacing is 126, rear derailleur is a Cyclone MK-II that maxes out on a 26t cog.

I'm planning a trip to the coop this afternoon but not sure what condition theirs would be in. I'd hate to put a new chain on a busted up freewheel.
