SPIRAL BALANCE REPLACEMENTS

I purchased the 29" Series 900 Spiral Balance along with the 3/8" thick Pivot Shoe. I didn't realize it at the time, but I also need the Pivot Bar. Does item 26-297 Pivot Bar fit the 15-045 Pivot Shoe? The bar was completely rusted away so the only guideline is the distance between screw holes. I need the bars as well as the applicable screws.

The distance between holes on the Pivot Bar 26-297 match the holes on the bottom of the window sash. So, does the Pivot Bar 26-297 fit into the slot on Pivot Shoe 15-045? The thickness of the Pivot Shoe (15-045) that showed with the Balance is 3/8" and that matches the old shoe. (The old shoes are filled with rusted Pivot Bar so they can not be reused. I need to assure that all the parts work together.

Thanks
