Window balance lower sash pin

Hello

Attached are pictures of a pin from a single hung window from the bottom side of sash that push into the balance shoe. Can't seem to find this part anywhere. Smaller tapered end is part that pushes into shoe and remaining part is pushed into window then a screw holds it in place from the bottom side. Measurements are 2 1/4" L x 5/16" W x 3/16" H Any help would be appreciated.

Thanks Again-

Steve

Found pivot pin 26-297 which appears to be an exact replacement. Which part # would be the corresponding pivot shoe and spiral balance series? Ones being replaced appear to be the red ones.
