Need to Find Replacement Crank/Assembly

Quick Learner from Chicago
Hello,
Trying to find replacement assemblies for 7 windows, six of which open to the side and one opens from the bottom. All are marked Norco. Other markings are Entry Guard and 20755. Most of them broke at the bottom of the piece that goes into the gears and attaches to the handle. They are from the mid-1990s.
All of the windows measure between 22.5" and 33" wide.

Thanks for posting. I recommend starting with our 39-031 (and its opposite 39-032). Carefully review and compare the measurements to confirm if this is the right fit for you.

These are compatible with the 39-107 cover and the 39-114L crank handle.

The top right bar on mine is not as long. It is a little under 3"

Thanks for confirming. It does appear that your link arm might be just a bit longer than 3" however, it could be a trick of the angle. Based on the confirmed measurement, I recommend taking a look at our 39-333 and its opposite 39-334. Carefully compare the measurements below to determine if this the correct replacement for you.

I must have not measured correctly - the right bar on mine is a little less than 4 inches. What would you recommend?

Since your link arm measures a little less than 4", I recommend the 39-155 and 39-156. Take a look at the diagram below to confirm the measurements. I believe this is the operator your are searching for.
