Steve, both ends of the original spool holder are not bent at 90 degrees, I've taken 2 more pictures that include the original and duplicate spool holders. I hope you're able to view the slight angle bend at one end of the original spool holder. I also cleaned the original spool holder that is why the metal looks so bright/new.
