The following photo has been posted over on VMF, I asked about the blue alternator fan and pulley and got no response. So Ill ask here. I cant say Ive ever seen this before, or at least never noticed it before on any concours cars.... Jeff , Charles , Whats your take?
Discussed a number of times - check the 65-66 section of this site for at least one discussion here.
Basically an oddity that popped up here and there (no really hard pattern identified yet that I'm aware of) in San Jose and Dearborn production. Don't think you'll find many concours cars with them since the percentage that got them, again was very very small - and no one want to be the guy with the blue alternator fan
