Issues replacing pivot bar

A quick learner from Greenwood, SC says:
Hi, I thought I'd ordered the correct replacement pivot bar (265B) but apparently I was unaware that the former bar had threads in it. The hole on 365B is also just ever so slightly smaller than the old screws. The hole lines up fine with the existing one on the sash, so other than these issues I cannot think of why it wont screw in. Can you help me find the right bar please?

Hello,

I don't believe that we carry an exact replacement for your pivot bar but the style is similar to the 26-030, 26-226, and 26-450. To determine if one of them could work for you, you'll need to compare the installation hole backset, as well as the height and width that engages with the pivot shoe, to your original part. Take a look and see what you think. Thank you.
