The thread sizes on the threaded end of the tie rod ends MAY be the same (My experience tells me, IT IS NOT), BUT also the tapers on the tie rod ends are not the same. The tapers are larger on the 73-up tie rod ends. 71 and 72 tapers are the same , BUT also different form 70 and earlier.

I just completed a 70 C30/35 to 86 Disc Brake Conversion and the 86 tie-rod ends... ARE... the same taper as the 70. I reused my 70 center link with a 70 Pitman Arm, a 70 Idler Arm and 86 tie-rod ends inner and outer, they are the same taper and fit perfectly.

Now the 86 center link which is a different length, about 1-1/4" shorter than the 70 at the Pitman, Idler taper centerlines and 1/2" shorter at the tie rod tapers, cannot be used...it does have one size smaller Idler Arm Taper, but the frame Idler brackets are the same taper.

Here are my notes I posted on what I used to complete my conversion:
