T5 in a stock automatic el camino

Im building a 1982 El Camino, came stock with a 231 V6 & Turbo 350 auto trans. Swapping for a small block 400, I have the engine and tranny but am still trying to figure out the clutch. Were there any models close enough in design to the elky that I could use a clutch pedal assembly from without too much jerryrigging? Any recommendations for the throwout? any help is appreciated, Thanks!
