Fan clutch problems...

The other day i heard a grinding noise coming from the motor. My fan clutch was going out. So i pull it off and go to autoclone and see if i can get a new one. Well they dont have one like mine. So i go to another shop and see if they have it.. nope, also they added that i had a weird fan clutch. The ones they show me have four holes all same length from each other that you screw bolts into. Mine has studs sticking out but besides the four studs it is two more, so a total of 6 holes. and the 4 are further away. No one had these so i had to chunk the clutch and swith to a spacer and a flex-a-lite fan. Its not a problem any more just wondering if anyone knows about this???

*edit* Its in my 71 chevelle with a 350

My 72 Nova with 350 came from the factory with a 4-hole thermostatic fan clutch. Yours may be non-original.

Most original pumps came with studs. For the straight fan the studs have to be removed and bolts be used. It was good to catch it early or the pump would have wiped out the bushing in the pump. You shouldn't have any problem with the setup the way you changed it. Most pumps come with 2 different bolt patterns for different applications, even my new aluminum GM short pump has 2 different sets. They use the same nose piece for the short and long.
Luv the smell of NITRO in the morning.
