Please help me find a replacement wheel for my windows

This is very similar to our 81-247 wheel assembly, but with a straight tab. I think ours should still work, even with a bent tab. The only difference that makes is pushing the roller deeper in, but there should be plenty of room for this. Let me know your thoughts!
