Give Mark or LT a call at Metal Tech. They can hook you up with all the parts and provide a lot of advice. My rig was one of the first to get a 2" TC long travel up grade back in 2008 and they spent a long time discussing all the components with Total Chaos and Sway-A-Way engineers.
Also if you will be doing it yourself make sure you ask Mark to include Toyota seals, hub cover, boot kit and lube. TC would have you re-use these parts. Mark and LT's experience with FJs paid off since they went ahead and picked them up. After seeing what the seals looked like I was was glad not to reuse a few dollar part on the new suspension.
BTW: if you are going to do the install yourself here is a good video on
taking apart the FJ Cruiser half shafts. Mark uses an old school FJ trick rather than cutting the axel as TC recommends.
here is how my rig turned out... I would do it again in a heart beat... best mod I've ever done to the rig.
Good luck to you
