The Auto-zone online catolog shows the 4 sp automatic in 1984 for the filter. The same filter# is shown with the I6 in 1984.
The carburator on my 1980 (California emissions) shows the same part number for 1984 (with federal emissions).
My guess is I need to see the trans cable hook-up, get the cable as I figure is probably longer than the 350 v8. Oh and build the trans, but I have that.
I may have to put off body work materials to get the tranny parts.
or not
My motor runs so lean I should be able to get 35 mpg. Ha ha
