pivot bar replacement

I am needing to replace several pivot bars on unknown brand vinyl tilt windows. It appears that your # 26-226 is a close match although as you can see, the original bars are only 2 11/16 or 2 3/4 long and have one hole 1 3/8 or 1 13/32 from the end depending upon the reference point being the round disk or the retangular bar. Also, only one screw hole is present although the windows themselves have a slot where an additional screw 1 inch from the first could be placed. It appears the window channel will accept a longer bar without difficulty. The only marking on the bar appears to be a # 7. Is the 26-226 the correct replacement? Thank you very much for your assistance.
