I am finally getting around to changing the gear oil in my truck. Which should I be running in my 1969 W300. It has Dana 70 axles (rear has a limited slip), NP435 trans, and NP205 transfer case. I was reading posts from past forums. It seems like 85W140, GL-1 was coming up a lot. I can't seem to find any GL-1 gear oil locally. Let me know what your thoughts are. Thanks in advance.
