Thanks! I didn't think the taper changed. But all of my cars are '70+ and when I saw it was a different part number I didn't want to mess anybody up. The tie rod end part number change is '70, so, '63-'69 is listed as ES319R and ES319L and '70-'76 is listed as ES401L and ES401R.
Totally agree on the tie rod end, the boots will need to be changed if nothing else because it's hard not to damage them during removal even if they're brand new. And if it's going to be apart and they haven't been changed recently now would be the time to change them.
