I'm attempting to convert an older freewheel hub (see bottom of page here: http://www.parktool.com/blog/repair-...ewheel-removal ) to a single speed (single cog spaced out with multiple spacers), but have never worked with a non-lockring style freewheel. Are the threads on these older style freewheels the same dimensions as modern cogs/lockrings?

Any help would be appreciated. Thanks in advance.
