On that type of differential with that year truck, your best option would be find good used third member simply because differential work usually means special tools. Also make sure you have the same gear ratio if you find a used differential.
only if its the Dana 40 or 60

I own a 1984 F150 XLT with a 351w (5.8 liter) and a 4V Holley carb. I 'just' had the differential rebuilt and the Ring & Pinion gear ratio that was in there was 3.0. It is a 9" Ford differential (stock). I had it replaced (it was worn anyway) with 2.75 ratio for better highway driving. I am not sure about the HP, though. My truck is wholly stock and I have been giving it a 'rolling restoration' since my late brother passed away in 2006 (I inherited it from him).
Neptune has five main rings surrounding it. The rings of Neptune appear to be a reddish color. they were first discovered in 1984.
It's either time to change your PCV vale and clean the lines or your rings are wore out or broken.
The system will need to be drained of Freon and pressure. Then the lines can be removed and the compressor replaced. Change all o rings during the procedure.
