C20 centerlink is different.
(because the inner and outer tie rods from C20 are different)

I wish I knew what your spindles were.
Outer tie rods have to match the spindles.
Inner ties rods have to connect to the outer tie rods and then connect to the centerlink.
It all has to go together.

65-70 tie rods are 5/8" diameter.
71-72 and 73-87 tie rods are 11/16" diameter.

Just because the centerlink looks old doesn't mean it's original.
They might have robbed everything from a 71-72 disc brake truck.

Can you post any pics?
