I have a similar problem going. I need to find a fan clutch that is about 1/4 to 1/2 inch shorter. My fan hits the radiator under hard acceleration.

I tried to get a shorter clutch and nobody carries one any shorter than 1 1/2" from fan blade mount bosses to the end of the shaft that bolts to the pulley/pump.

I tried a Northern brand aluminum radiator with no luk, it won't mount any better than the stocker 26" one that is on there now. That one is sort of shoved in there as it is a 22" core support.

I haven't had any luck finding what I need to make it work. The factory aluminum blade fan that I have on it must flex under hard load as it is fine unless it is floored.

I have a Schemaker adjustable torque strap and it isn't roking side to side but ight be inching forward somehow.

Anybody know of a shorter clutch than what I described?
