Staton-inc sells a 5/8 inch to standard freewheel thread adapter.

Several scooter sites sell the inexpensive flanged freewheels, with an approximate 3 inch diameter bolt pattern on the flange for 4 bolts. Sick Bike Parts (an MBC sponsor) sells similar ones as well, plus, they also sell a heavy duty version made by white industries; their version has a 5-hole pattern.
