Riddler, you're being incorrectly too matter of fact. There's a few options for clutch/flywheels. Depending on the person's use needs and pocketbook:
3/4 ton Hemi Ram flywheel and clutch
Challenger flywheel and dual disc clutch
McCleod has several choices
Fidanza
SPEC
I'm using a SPEC flywheel / dual disc clutch for a Challenger application in my 392 Cuda
