I check O'Reilly Autos website.
It appears the idler arm is the same,... but the pitman arm is different.
Maybe you could run a 73-87 steering box and make it work.

You should be able to use a 71-72 inner tie rod and couple it to a '73-87 outer tie rod, since they are the same 11/16" thread size.
This will allow you to use your existing 71-72 style centerlink.

On a side note:
(you can't do this with the 63-70 inner tie rods because they are the smaller 5/8" tie rods. Unless you use a "conversion" tie rod adapter that companies like CPP and PerformanceOnline sell).
