Are the tie rod ends the same from 63-76?

No -- they are not the same -- the angle is slightly different -- and enough so -- that you can not get accurate alignment....
1962 - 1969 are the same ---- ES319L (Inners) and ES319R (Outers)
1970 - 1976 are the same ---- ES401L (Inners) and ES401R (Outers)
The 70 - 76 are far less expensive than the 62 - 69s......
