Viscous fan package?

Bob, I am trying to put all the bolts in my Hayden 2947 fan clutch. It is more difficult than I even imagined. I had one bolt in for mock up before. I am trying your stud method now & that is even hard. Any other tips?

I didnt use studs this time , I used a hair longer grade 8 bolt w/ a flat washer .
I cut the lip off of the back of my clutch ,about .100 , wish I`d have gone another .20 or .030, that lip doesnt do anything , and is just extra mat`rl.
I still had to install one bolt ,"leave ''unscrewed'' a bunch, to set the clutch groove in , to help get the fan in position, and rotated it around ,starting all the bolts w/ it way loose , and had to use needle nose pliers to get it in position ,( I WAS DOING IT W/ BURNED FINGERS ON MY RIGHT HAND). If u tighten one to far, u cant **** the thing out enough to get all of them started. w/o cutting the lip off , I doubt I could have done this ,then it would be back to using the studs , u can cut carburator studs to the exact length < trial and error .
Cutting the back of the clutch can be done easy in a lathe , my lathe took quite a bit of imagination because it wasnt big enought to swing the clutch over the cross slide , I would recommend having it cut by a machinist , would be ''no big deal.''
HANG IN THERE , ITS STILL A ***** !----LOL
