Mani differences are body panels particularly nose and tail. Tail is the same until 79-81. Nose and matching front spoilers also changed then.
79-81 rear discs were an option. 79-80 used a cast iron master cylinder . 81 went to an aluminum "quick take up MC with a bigger register and booster for the "low drag" calipers they started that year. 81 also used a different size upper A arm bushing.
My 78 TA the water base started wearing off between the T tops and left sail and quarter panel right after it was out of warranty!
Bottom of fenders front and back common rust spots.
