The T-100 rear is exactly 66.75" wide and uses the standard 8.4" third thats in the Tacos. So yes, you can get 5.29s for them. I have one under my '00 Taco with a HP Dana 44 front. They work great together. Good luck with your build man! And why does everyone always overlook the T-100 and Tundra rear when trying to go full width?
