Which tranny is more correct for a resto?

It depends on what you are going to do with the car. If you are going to show it, then you need to find out what the judges guidelines are. Unfortunately I don't think there is a written guideline for some cars like the NCRS has for the Corvette. Each event might have different rules.

If it's for personal satisfaction, then you can set your own rules and do what you want. I'm in the same situation and have decided to go with a correctly dated tranny. It's the closest I can get to what came in it from the factory. JMO.
