Mine is a 72 dart. It had a /6 now a 340 with a champion 3 core radiator. I have the new hayden clutch and it gives me a little over a 1/2 inch. I also have a motor mount swap kit not sure what brand. I hope that helps

I`m skipping most of these posts.

I have one of the new short clutch type laying on the bench, it was as close as one of the real early pics w/ about 3/4' clearance, it does have the slotted holes, and the bushing for our smaller shafts. It does take a regular mopar fan designed for the clutch types.
The only reason I am not using it is "I believe" is, my engine is kind of on the edge for a streetcar , and the outside diameter of the clutch it self blocks airflow to the fan. The same size fan w/o a clutch of any kind cools better than the clutch for me.
I have enough under hood heat, that its melting the plastic vents I put in my fiberglass hood , on the hottest summer days.
The new clutch measures exactly 2 5/8" tall , laying it on the bench and measuring to a straight edge laying across the face of it.
IT IS FOR SALE IF ANY ONE NEEDS IT . Comes w/ the studs and nuts I used ,only ran for about an hour .
It will more than likely work for a lesser h/p engine---------$40 plus shipping form 74021 BOB

What I mean is that the 2747 Hayden is easy....The shorter one is about an inch shorter. Bolts are tough to fit in and thread, nuts over studs require smaller hands with greater dexterity than I have.

THIS IS TRUE ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ITS SOME WHAT OF A ***** ! I did machine an alum. ring that press fits around the slotted holes , makes it even harder, but is still doable .

Do you have a fan shroud?
 
True
I also recall the mounting bolts had to be a pretty precise length
Too long and you could not fit them in the area to get started in the holes.

How i bolted mine on was to hold the fan out away from the pulley, get one bolt started, then turn the fan and pulley to get the next bolt started etc, then tighten them down all a little at a time until its seated and torqued.
