Sorry, brake mountings are different.

Steering knuckle for '86 is

Manual steering:
251 407 311 AG left, 312 AG right.  Says also use 251 407 631 spacer ring.

Power steering:
251 407 311 AQ left, 312 AQ right.  Says also use 191 501 159 plug
and N 014 750 6 M6x10 Allen head bolt, one each per side.

This is book knowledge.  The power steering knuckle give you faster
steering; I believe they're otherwise interchangeable but you'll have
to hear it from someone who actually knows.

Yrs,
