Wondering if there is one, or if not, can we start one? Personally, I have a 58 FC170 and I would just like to know what fluid to put in every fluid-filled orafice. I can find a few here and there through google, but a consolidated thread would be nice.

Super Hurrican L6 engine oil:
Coolant?:
Dana 44 closed knuckle front GEAR oil:
Dana 44 closed knuckle knuckle oil:
Dana 53 rear gear oil:
T90A? 3 speed transmission:
Dana 18 T-case:

Also, was told by an aged master tech (not necessarily familiar with willys specifically) that in some older engines, you want an additive in the gas? Is that true or is good ol' 85 good enough?
