985 2-B
Hello! Looks like your old pivot bar is rusted out and in need of replacement. My top picks at this point are the 26-040 pivot bar and 26-382S housing (sold separately). Review their specs below to verify that everything matches up. To remove the old bit of the pivot bar from the pivot shoe, soak it in WD-40 overnight and see if you can pull it out with pliers.
We unfortunately don't sell a pivot carrier with that exact size. I can only tell you that our 26-382S is our closest match, though if the dimensions don't match then I'm not optimistic that it will work.
As for the tilt latch, you might have our 26-408. Once again it will come down to dimensions. I highly recommend reviewing ours to confirm that they line up.
