1980 GMC cooling fan question
hi all, i'm seeking to contact the manufacturer of a fan blade that was installed on a 1980 GMC truck, 350 engine, that I bought about 2 yrs. ago and am just getting around to fixing. it is defective and i want to get the specs b/f i order a new one. it doesn't have any parts numbers on it but it does have a fairly unique rivet pattern that I figured someone on here could identify. i can't figure out how to post photos here, so email me and i'll mail you a few photos. Thanks for any help!
