[DeTomaso] Will a twin disk clutch with a Borg and Beck Long stylepressure plate fit?

[Paul - Home]

The main reason racing clutches are small diameter is to move the the 
rotational mass closer to the center line.  The switch to multiple disks 
is done to insure that there is enough friction surface.
