Thanks for the info. I thought I would be out of luck. None of my local bike shops had a replacement and most of the younger folks and never seen this type of freewheel. An older fellow at one shop said he used to ride with one and said it was a very good quality freewheel in it's time and would be hard to replace locally. Thank goodness for the internet.
In final stages for refurbishing my old bike. Just have to put the rear wheel on and adjust the gears. Will see how they work.
Didn't realize I could upgrade to a 7 speed. Food for thought.
The IRD freewheel does look nice and yes it's expensive at $59.99 USD vs the Shimano. Converted to CDN it comes to about $77.00 plus shipping. Ouch.
