Here's what I would use:

Motor: 15W40 Rotella for Conventional or Mobil 1 5W40 for synthetic (Make sure any oil you use is Diesel rated)
IP: I believe this called for a straight SAE30 without detergent - check manual
Coolant: Mercedes Brand or Xerex G-05 (either one 50/50 mix with distilled water)
Brake Fluid: any DOT 3 or DOT4
Axle: Mobil 1 75w90
Transmission: Redline MTL or any Dexron ATF you care to use

I'm sure others will have their own suggestions
