The factory 2-groove pulleys are getting extremely rare. When we have used ones available we usually get $50 apiece for them just for that reason, and we don't have any currently because they do get snapped up so quick even at that price. There are some chrome aftermarket ones available but beware of those, they're junk and will split. IMO the best setup are the billet pulleys from Wild Horses. We use and install those fairly regularly and they're a great product. They look awesome too.
