[MENTION=226065]Metacortex[/MENTION], are you sure about that CT-3 tool? The link you provided for the United Maillard freewheel tool looks right, but the link for the CT-3 doesn't appear to be the right tool (low, flat splines instead of the angled splines seen on the OPs freewheel).
Someone correct me if I am wrong, but I think this may work (~$10 with shipping):
