I’ve read many threads on this wirh many opinions.

1971 duster with a903 . 3 on tree style trans . It’s great and I’m in proses of converting to 4 speed overdrive but in mean time I want this thing to have fresh fluids before power tour .
What is supposed to be in this ? ATF ? Dex 3 ?
what about the 7 1/4 rear ? What oil or fluid for that ? I’m trying to get all stuff to do this this weekend.
