B&D older miter saw w/5/8th arbor?

Do you know of any after-market laser product which would work on this saw? I purched 2 and had to return both as the hole was to samll, thiese were the ones that go on the saw blade. The arbor on mine is 5/8th and I can not find one with that size hole. Or is there a universal product which will fit on the saw itself? Am in Denver Colorado.
