I just replaced my water pump on my 63.
When I installed the Idler Pulley Assembly the nut, lock-washer and flat washer didn't look correct so I changed them out to black oxide from Zinc. I have no idea which is correct as it isn't mentioned in the JM. The JM did identify the long hex stud finish as black oxide or black phosphate.
Below are the part numbers out of the assemble manual.
120377 Nut
446212 P washer
120382 L washer

Can anyone identify the correct finish for me?
Thanks
Rick
