I find it utterly insulting and unacceptable that I was mentioned in the same sentence as Hubert. That's it! I'm leaving!Rich and NotHJF, you're never allowed to rage-quit this board.
Wait, where else would I go? (slinks back in with his tail between his legs)
On a more serious note, when replacing the rear sway bar the factory links are more than up to the task of being reused (unlike the fronts) but it is a really good idea to replace the link bushings. They are a lot easier to install if you get the two-piece split bushings. (I'm not even sure anyone sells the one piece ones anymore.)
As far as the rear subframe bushings, I'd strongly suggest you go with poly and not solid bushings.
