Can I replace pivot bar with slightly longer...

I've got a couple old vinyl windows that I can only guess are just warped or worn because the 2.5" pivot bar ( 26-083) just keeps popping out. I replaced every single pivot shoe and bar on one window, and within a few ups and downs one side or both pops out.. Both sashes have this problem.

I was thinking of trying ordering this 3" one instead. The hole spacing on the first 2 holes is only 1/16" different.. I'm pretty sure the vinyl is worn enough to wiggle that much. And comparing the drawings, if I use those first 2 holes I'll get it sticking an extra 1/8" out the end.. I think that 1/4" total (if I do both sides) may be enough to stay in, while not so much to jam up where it's less warped. Just trying to get a couple years out of them before I replace them all with a nicer window.

Was thinking to avoid the high shipping costs, I would just order a bunch. If I it works, I'll keep them for other windows. If it doesn't I'll return them. I've got a few pivot shoes (wasn't positive of size and double-ordered) to pay return shipping on already anyway...

Am I nutz? Seems no harm as long as there's enough give in the screw holes in the window that it doesn't wear them down to the point I can't get the old bar back in if it doesn't work.... Seems like there should be enough slack for 16th of an inch (difference in hole spacing between the 2 bars)?

For those who may find this.... I went ahead and did this and it worked for my situation. A couple caveats... I really had nothing to lose. With the sash popping out of the shoes in my 6 year old's room, I wasn't about to risk the window dropping on her. So worst came to worst, the window became inoperable, which for my purposes it already was.

So.... a couple of things to note:

The shorter (original to the window) pivot bar I referenced in my first post uses #6 screws. This longer one uses #8s. So aside from buying new screws if you don't have them, you need to be OK with drilling (or just letting the screw tear) a slightly larger diameter screw hole in the vinyl sash. Don't know what the impact would have been had this failed (i.e. had the longer bar jammed the window) and I had to go back to the original bar. Probably would have been fine - might have needed a washer - but just a disclaimer, I can't say for sure, may have been too much wiggle and I may have been up the creek for good.

Additionally the hole spacing IS definitely off by that 1/16th of an inch the drawings show and it's not totally negligible. Again, vinyl has enough give that it worked - but unsure what the impact would be if I had to go back to the old pivot bar had this not worked.

All of the above is why I only did one side first. That seems to be working, so unless it starts popping out again, I plan to leave it rather than risk going to far and causing the window to jam if I do both sides.

Note, I also silicone sprayed the shoe track and white lithium greased the spiral balance (found on another helpful post on here!) - so I'm not jarring the window as much, which I think is also helping. It popped out easily enough before, however, that I don't believe that alone would have solved the original problem.

Final Note.... I have new windows on my "5 year plan"... so again... not a lot to lose. Personally, I probably wouldn't have tried this on a newer window. But hopefully a newer window wouldn't have such a warped frame that this was happening in the first place! Fiberglass for the new windows when the time comes :-)

Hopefully this helps if anyone runs across this post with a similar issue!!
