Some months ago, I was removing a nice, lightly used Suntour Winner Pro freewheel to install on a different wheel. I managed to sheer off one of the four prongs (see pics)'so now four prong removal tool doesn't grab the lower notches. I managed to get the freewheel off but it's been sitting in a drawer for months because I feared installing and then being unable to remove should I want to in the future. The freewheel spins nicely, and the cogs are in almost new condition so I'd like to use it. Is the center body a replaceable part (assuming I could find one)? Is freewheel likely removable even with damage?
