Can someone ID these 2 mystery trans?

Hey everyone:

I got a couple small-block 904's with a parts car recently, and I'd like to narrow down the years of possible:

First trans is supposed to be non-lockup 904:

Rail: 2892029 2670650

Case top: 2538 473-1

67 ()()()()()()()()()() <-those are boxes

Next trans is supposed to be a lock-up 904:

Rail: PK4028815 5856 4485

Nothing on the top of the case.
