Window part?

Hello,

I need 4 of this part for which I do not know the proper name. Anyway, they are for a Wenco tilt window and are the part that the pins on the lower window fit into. The top part that is broken off is where the string attaches and id the string on the other end goes to the spring balance. They fit into the side rails of the window, one on each side.

As shown, the part is 2 1/2 inches long by 1/2" wide and 1/2 inch deep.

Please let em know if you have these parts available.

Thank you,
Ted

These look like they will work.

I will try to order them now.

Thank you very much for all of your assistance,
Ted
