Be careful if you are only trying to replace just a hub or a spider as there are numerious Brands such as the Giflex, Rotex, KTR & FBX which are dimensional very similar but are not interchangeable? Therefore close attention need to be paid to the pitch of the spider as the can differ slightly? If in doubt replace the complete coupling!
