    f body t56, heavy duty clutch (ls1, ls2,ls7) style dont go with a stock ls1 clutch. i dont even have a thousand miles on it yet and shes burned up already. f body thowout bearing, 02 fbody slave, your driveshaft will be the same. a sweet shifter extension will be needed. i cant remember if i am missing anything here. im sure someone else will chime in

    alos 5 speed truck trans crossmember, clutch pedal assembly out of a manual truck, theres alot of write ups on performance trucks on renforcing the clutch pedal assembly so it can take hard shifts! gotta find that, think the 6 speed swap is the way to go these days...ive already started gathering parts for my swap as well!
