I once had a '66 that was a factory Powerglide. The parts from that truck would be exactly what you need for a Turbo 350. My brother made the swap on a similar truck, and if memory serves it was a simple bolt together swap.
He used the original column and shifter with no trouble. I have a '72 with a tilt column and automatic. You can't have my parts, but again, they would be just what you need if you can find one.
