[DeTomaso] Centerforce dual friction disk from Ford Racing

[Will Demelo]

Don't know about the 700000, but I'm 100% sure the DF021057S doesn't bolt to 
the stock flywheel.

>>Ken, you want to keep in mind that some of the clutches- Centerforce

>>not something you want to attempt with a a hand drill or even a drill

>>Getting the 16-lb clutch off-center even 0.010" will give you an engine

>>shakes like a wet dog!
>>Other aftermarket clutches also use their own bolt patterns. If you factor
>>in the cost of a new flywheel, the price of a Centerforce setup changes
>>appreciably, but once you own a 'racing' flywheel, many are drilled & 
>>tapped for
>>as many as 4 different bolt patterns & sizes.
>>Centerforce also comes in a variety of clutch strengths, too. I've driven 
>>a

>>'Heavy Duty" clutch, and if one was given to me free, it would be on E-Bay 
>>within

>>before, you need to have a firm idea of what you want out of your Pantera
>>before doing redesigns.
>>Good luck- J DeRyke (still running the OEM clutch & disc at 80,000 miles
