Currently in the process of changing out my A/C belt and idler pulley on my '89 Z31, bought the new idler and belt, but the new pulley is the one that fits the 11.85mm shank idler adjuster, and the old one is th 9.85 - annoying, but whatever - I plan on ordering the new idler adjuster with the 11.85mm shank, but my main concern is the bushings/washers that go along with it. From what I can tell, the previous owner did not have the pulley set up properly in terms of spacing, and I also have no clue in which order any of the spacers are meant to go - also, if I get the bigger shank adjuster, it seems that I would have to buy new spacer(s?) anyways?

New to the forum, so I apologize for any etiquette I may be skipping over.
