I have just picked up a used 2 piece Henderson 7mm suit. The suit is in good condition but The pull tab on the Jacket zipper is broken off. The zipper still works but to be able to pull it up and down the old owner used a wire tie for a replacement. Is there any way to replace just the pull tab without replacing the zipper? Does anyone have any ideas on how to make a better repair than a wire tie? Thanks for any advise you can provide!!
