It's ok, I can measure mine in the mourning. I didn't take a tape with me to the junk yard and should've measured the fan. Think I'd have to up the alternator? Thanks.
unless you go with full speed lincoln mk viii i think you're fine with the stock alternator (if it's a 90 amp, for some reason i kind of remember there were some 60 amps or so out there as well but can't tell you for sure, if you have one of those would be preferred to upgrade).
