My OEM chrome (plastic) alternator cover deformed as many do over time. Hate looking at it and have gone to the stealer, as well as ebay and Amazon. It was always hundreds of dollars. Just couldn't swallow that pill.
I found Web!ike (
https://japan.webike.net/) and they had the OEM part (21333MZ0A00) for $53.98 to my door in the U.S. (No affiliation, ect, ect.)
Got it today (less than two weeks) and it it is perfect.
Shine em if ya got em.
Sparky.
