Thanks for the link. Most of that stuff is interchangeable, but you never know when they'll make something that's not quite right. I was reading online about an issue with round vs square starter pawls. Fortunately all I need is the pulley, so this one should work great.
By the way, Harbor Freight doesn't support discontinued items. You know those companies that go the extra mile to figure out what you need? Harbor Freight isn't one of those companies. They just have a bunch of monkeys sitting in cubicles saying "Uhhm.... that isn't on the website". They don't even try.
