Changing 4 speed to auto. What else do I need ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm changing from my NP 435 4 speed to a turbo 350. Ive got a used but serviceable turbo 350, a new filter kit, a rear mount, a new set of seals, a new torque converter, a B&M shift kit, a Lokar shifter, and an automatic crossmember . What else will I need. I havent measured the OAL on the turbo 350 and the NP435 yet but I assume I'll need a different front driveshaft and a different transmission yoke from the junkyard . Anything I am forgetting? I know I need a flexplate too.
