Gorell tilt window pivot bar

I have a Gorell tilt vinyl window and the pivot bar snapped off when removing sash. The bar measures approx.3" long and about 1" from the end, it has one single screw hole. Everything is rusted. I have replaced the mounting bracket wit your 6-o24, 15-o87 coil housing pivot, 15-086 tandem coil housing and (2) S-187 , 7# coil balance springs. Any idea or references for the Pivot bar for the Gorell? I think the profile is about 3/16' high and is U shaped but can't be sure. Thanks.
