What I have is an original chevy fan.,
it has a G68 1968 date on it, might be date correct for 68 or 69 , I believe this came on cars with factory AC
so it might be for 68 camaro , firebird , corvette or something similar
I just saw one on ebay without the fan clutch for $750!!!
I am asking $375 for mine
just send me a reply if you are interested , if this ad is up then the fan is still for sale
