WANTED: Lower Belt Pulley For A Col AT

I mailed an AT mechanism, thinking it was well packed, and the lower belt pulley was damaged and is unrepairable. I'd like to buy a replacement. Is that pulley common with other Columbia models? Thanks for checking your parts bin.

I have the lower belt pulley for an AZ. I'll provide dimensions later. Maybe it will fit.

Here are the dimensions: Diameter is 2-⅜ inches. Width is 7/16 inches. The inner hole diameter(for the arbor) is 3/16 inches. I don't have the set screw, but good chance is the same if the pulley is the same.

Jerry asked me to post some pictures if the damaged pulley. The flange diameters are 2 5/16", The actual functional pulley diameter is 1 ¼". Width between the flanges is ⅜". Through bore is 3/16". The material appears to be a nickel plated brass casting.
