[DeTomaso] Centerforce dual friction disk from Ford Racing

[JDeRyke at aol.com]

Ken, you want to keep in mind that some of the clutches- Centerforce 
especially- will NOT bolt onto a stock flywheel. The Centerforce clutch cover uses 
a slightly different bolt pattern and larger bolts, with stand-off washers 
and different torque requirements. And redrilling & tapping a flywheel is 
not something you want to attempt with a a hand drill or even a drill press! 
Getting the 16-lb clutch off-center even 0.010" will give you an engine that 
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 
Pantera with the effort-reduction linkage installed and a Centerforce 
'Heavy Duty" clutch, and if one was given to me free, it would be on E-Bay within 
the hour. Second-most uncomfortable Pantera I've ever driven. As I said 
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 
and will use it with my Fontana, too)
