I agree, on a street car, full or near DD, the replaceable inserts on aluminum flywheels are a big PITA once you have burned out the original one--they never seem to fit properly and often (again for street/DD use) require that you pull the f/w and have the new insert turned to make it tolerable. If I had one (and I have, and did) I would just do that routinely when replacing the insert.
Two of my friends that had their aluminum flywheels fail were
Spec aluminum flywheels and I don't think it's a coincidence either.
Another Spec product fails.

One more thing...I would like to get ARP flywheel bolts but I am having trouble finding which ones are the correct ones to get.
FRPP sells this kit of bolts which is supposedly for all modular 11" flywheels: http://www.fordracingparts.com/parts...tKeyField=8457
it's 10 mm X 1.5
But all other sites which sell the ARP bolts for our cars list this one:
http://www.summitracing.com/parts/ARP-254-2801/
Which are 10 mm X 1.0
Anyone know which size is the correct one for my 04 GT?

You can use a pin punch to drive the dowel pins from the old flywheel and reuse them (drive them out from the front-to-back of the flywheel).
Here's the procedure from the shop manual.
They are vital to properly aligning the pressure plate assembly! You WILL have vibration and odd-engagement is they are not used, and I have seen more than one botched installation where they were not.
The gasket was for the passenger side X-pipe to exhaust manifold connection--it came out in pieces and had to be replaced. You may want to pick one up "just-in-case", or just to replace it anyway...

It looks like the ARP might be for the Cobra FW (8 bolts).

Spec's products, like most things made by man, fall into two broad categories; those that work and hold up well, and those that don't.
The problem with Spec specifically is that their stuff which falls into the second category seems to be a dis-proportionally large chunk of the total, much higher than with most manufacturers--there is no way I'd install one of their clutches
(FWIW, these are individual photos of separate failures, accumulated from the web in less than 5 minutes using Google).
