1975 A833 od, any useful parts for non od boxes

Thank you everyone for all your responses, I always learn a lot from this site and you folks who are willing to share your knowledge and experiences.

I have decided to keep all three of my transmissions, the 2.47 box in all aluminum direct connection case, the cast iron case 3.09 OD, and the 1965 3.09 non od box I have coming. This certainly isn't my last Mopar and I'm not an automatic guy at all. Who knows what I will need down the road, these things are not exactly falling from the trees anymore.
