[DeTomaso] PP bolts for Fidanza Flywheel

[Ken Green]

They offer several different 5/16 18 studs, and one may work well.  I also really prefer studs into aluminum.
 
There are other studs at McMaster Carr and other sources, and they have some nice 12 point flange nuts to go with them.

I think that may be a good solution. You'd probably want to keep the unthreaded portion to a minimum so you didn't have to stack a bunch of washers to accomodate it.

I found these 5/16 grade 8 studs:

Maybe that is a better approach for attaching the PP to the Fidanze flywheel?

The stock iron flywheel and clutch used shouldered bolts and recesses
countersunk in the flywheel with no thread so that they could be fully
torqued without bottoming the threads. It was a very rigid, strong assembly
when done. Centerforce steel and aluminum flywheels for our cars are done
the same way. The Fidanza aluminum flywheel is the only one I've seen that
has no similar solution available. Stacking the bolt out with washers
doesn't satisfy me in an application like pressure plate bolts, but I guess
that's the worked for some people. The Fidanza is about half the price of a
Centerforce or Mcleod aluminum flywheel and I assume they are made to use
the original Ford bolts or an ARP equal? Maybe this is a case of "you get
what you pay for". It's a lot of cash though.

I think the bolts for aluminum flywheels typically do:

But the flywheel needs recesses for the full diameter unthreaded portions to
fit into.

  I don't remember my PP bolts have shoulders.  Though it's been a while
now.
