This board has helped me a lot... and lately my 2 Qs (97 with 107K & 99 with 117K) were making noises coming from under the hood and thanks to this board...I decided to replace all pulleys with OEM ones

I replaced the alternator and water pump pulleys, belts,... Wow... the cars are much quieter

I got my AC & PS pulleys... However:
* On the original/old pulleys, on the front side, there is a washer between the (black) dust cover and the pulley.
* On the new pulleys, the cover looks a bit different different with no washer between the (nickel) dust cover and the pulley. Also, the bolt that holds the cover is different from the old one

I am afraid to put them on unless, I am 100% sure about the washer

The new pulleys are Genuine OEM from orderinfinitiparts (they were the cheapest) BUT, I can't get them to reply to my emails nor my calls (Price I paying from not going with Joe)

Any thoughts... PLEASE...

ALTERNATOR / IDLER PULLEY 119256P003 - idler pulley upper
ALTERNATOR / IDLER PULLEY 119256P004 - idler pulley lower
CONDENSER, COMPRESSOR & LINES / IDLER PULLEY 119251P103 - idler pulley
STEERING GEAR & LINKAGE / IDLER PULLEY 119451P163 - idler pulley

Here is a link to a picture of the 2 new pullies with missing washers!!

Welcome--you seem to take ownership seriously--good for you!
note that your new OEM infiniti pulleys have a minor part# reviosion from the original issue.
You should double check the stackup heights, especially on the back side.
on the front side, what's really important is that the pulley remain in plane with the others.
i seem to recall similar the last time i changed pulleys, and I deemed it ok. really on the front side the idea is just to compress against the inner bearing sleeve while allowing the bearing body to spin freely.

Thanks 3Q Jay

UPDATE:
Yes, the new pulleys fit exactly as the old pulleys with NO issues
