Harvey double hung window - L bracket

A home owner from Califon NJ says:
I would to order replacement L-brackets for Harvey vinyl double hung windows (see attached pictures). These brackets screw into the side of the window, and the key at the bottom of the bracket fits into the pivot bracket on the tension cords in the window frame.

I contacted Harvey directly, they said that they do not sell these, and that I should contact you. Please let me know if you have these in stock (or need any addtional info), and lead time for shipping.

Thanks for your help.

Thank you for your patience in this matter. Unfortunately, after extensive research, we have been unable to locate a replacement for this pivot bar. The closest possible thing we can recommend is our 26-164. I cannot guarantee that it will work, but it is the best we have.
