Thanks for the offer Fred!
I got directed to the cooling chart at CRG. It had some good info on what the stampings are and where they are located.
I took a chance and gently removed some paint with my fingernail. Not expecting to find anything, I was totally shocked to see the original ink stamps.
Looks like an assembly line 396/375 or 427/425 fan and clutch by the info at CRG. Sound correct?
