Looking for these replacement parts

Thank you for posting. I think the pivot bar resembles our 26-226, while the pivot shoe resembles our 15-175. Please carefully compare this hardware to your own and let me know how everything matches up.

No, metal cams are not universal. You will have to make sure to replace the pivot bar with something that matches.

I'm not sure what that headless screw could be, but I do know that if you do not have a cutout already made in your jamb then you will need the jamb spreaders. Check out the video below to see what I mean.

Ah, I see. That screw is meant to adjust the jamb. It shouldn't obstruct the way your pivot shoe moves at all. If you feel it is, maybe scrape away some of the plastic that appears to be sticking up.

You should also make sure your pivot shoe isn't still in the locked position. You can tell if it is by looking at the cam. If the cam slot is horizontal, then it's locked. If it's vertical, then it's unlocked. You can only move the shoe up and down if it's unlocked.

Finally, you could consider lubricating the track a bit to make it easier to move. Try out a silicone spray, or maybe our 75-077 slider slicker.
