72 steel or cast crank?

Well - all those different replies certainly made it clear as mud............just saying.....:study: :grin:
I was too lazy to check my build dates, but my my '72 TB3 Duster 4 speed, and my Red '72 3 speed both have steel cranks in them.
It could be anything in there for a crank, because if the comprssion ratio is 10.5:1, then that is definitley not stock for '72...........so I would not get too hung up on the date - just verify what you can see with your own eyes or on paper.
