Balance Shoes and Pivot Bars

Hello,

I think your Coil Balance Shoe, Slate Blue 15-177, should be exactly what I need for my window, but I am having a difficult time finding the correct T-head pivot bar. The one I need is 2 & 11/16" long,and has one hole 1 & 3/8" from the end of the head.

Could you help me locate the correct pivot bar?

Thank you,

Kathryn
