Google Inline industries, they make PALS, and the Dubby saw sled. They have a lot of videos, including one that shows him restoring a Craftsman saw that starts out in bad shape.
I am sure you can find it on you tube also, but he is THE guy. If you decide to redo it, he sells the PALS, steel pulleys, and a link belt that really smoothed my Dads saw vibrations.
