flywheel manual transmission 6.1

The flywheel you need is determined by which transmission and what bellhousing you're running. You're running the tr 6060? If so, I believe you need the flywheel off the new challenger, and you need a clutch for the new challenger (or a ram or spec aftermarket made for the chally).

The mopar performance flywheel will not work to my knowledge with the tr 6060.
