Looking for Replacement Top/Bottom track for mirrored sliding closet door

Hello, Will. My recommendations would be the 23-246 top track and 23-272 bottom track. They're a little long, but they can be cut down to 69" with a hacksaw. Let me know what you think.

I do think our track will work, yes; at least, it will be compatible with your old rollers and your closet doors will slide comfortably on it. It may not perfectly line up with your carpet, unfortunately, but we don't have an alternate option that will.
