63 Dodge Dart, now let me see;)

I sealed up the transmission, then took it around the corner of my garage, pressure washed with my wet sandblasting attachment, it's now looking much better;) Actually not sure what to do with it, take it apart, or take a chance as it looks and sounds good inside. I would like to at least replace the tail shaft bushing and obvious gaskets. I'll be using a GPS type speedo, so not worried about the speedo gear.
I need a shower!
