To each his own but for me, and its original, I"d run 30wt. motor oil, 85-90 gear lube.
As far levels go you simply unscrew the plug on the back of the rearend and fill it till it wants to overflow... but be sure the vehicle is sitting on lever ground. Also, take the fill plug out of the tranny and do the same thing.
...and of coarse you know where the dipstick is to check the engine oil.

I'm sure others will chip in later with their opinions.

And welcome to the Stovebolt.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
