Fan Clutch
Had to replace the fan clutch on my 95, 5.0L got the replacement from NAPA everything hooked up ok but now it is real LOUD when winding up the engine, all I can hear is the fan can not hear the engine anymore. Anyway I lived with it this way until I took it out wheeling and discovered that now when the fan winds up I get a HUGH cloud of dust off the road from under the engine.
Got home and looked again it seems that the new clutch has a shorter spindle, the front of the fan is clearly visible behind the fan shroud. Now I need to figure out how to adjust to this configuration, or did I get the Wrong clutch and now need to replace it again. Temp is great but running with out the shroud is noisy.
If I thought I was going to have to buy two I might have gone electric.

As you know, the fan sucks air through the rad from the front of the vehicle and pushes it back over the engine. The shroud merely ensures that the air is sucked from infront of the vehicle and through the rad and not from behind the rad. What you probably have is the wrong clutch and therefore it is locked up. Until your engine temp rises the fan should merely be free wheeling on the shaft. Once it hits the high temp mark for the clutch it locks up and sucks air from the front, through the rad and over the engine.
Checking this is really easy - with the engine off and cool - grab the fan and spin it. Does it spin freely? If it does, then it might just be a defect clutch that has too low a high temp set point. If not then your fan bolts are probably through the hub and stuck in the clutch fins so it can't free wheel.

Aftermarket fan clutches generally suck. If I have have to replace one, I cough up the extra $$ and snag an OEM. I've never had an aftermarket clutch work properly. If you want your rig to sound like a Cessna taking off, buy aftermarket.
I sold aftermarket parts for 17 years and there's only 2 things I'd ALWAYS buy OEM- fan clutches and in-tank electric fuel pumps. My Ranger's fan clutch locked up once while I was driving through the Yukon Territory, and even then I waited an extra day in Whitehorse for a Ford clutch rather than slam an aftermarket in it the same day. I didn't want to run another 2000 miles home listening to a crap clutch roaring and sucking down $6 a gallon backcountry gas.
As far as your length issue, aluminum spacers are cheap and can be had in various lengths.
