I have a 94 both O'Reillys and AutoZone recommended the same fan clutch but my friend working on my truck says it won't fit I would post pictures but looks like I can't do that here. Where the fan clutch attaches to the pulley that attaches to the water pump is thicker than the one I have on there now by about an eighth of an inch maybe. He said he tried longer bolts but that didn't work I'm at a loss.
Thanks for your help
