T-56 Transmission Install Thread
Stock pedals should work fine as far as I can tell, you can adapt them to about whatever you want for the most part. There are some mechanical clutch linkage T56 setups out there, though I don't know that I've heard of anyone trying that in a Mopar just yet. You should be able to use whatever slave goes with the trans you get (Viper, GM, etc) if you go the hydraulic way. You're on your own for a master, but there are plenty of generic ones out there that you can get. The big thing is just trying to match bore and stroke to whatever slave you pick to make sure you have enough volume to disengage the clutch. You can tune pedal feel with bore size, but you have to have enough stroke to move the throwout.
Sweet looking car by the way!
