What are the modern equivelants to these oils & lubricants?

[vespistiSF]

FIAT W 90/M Oil (as used in transmissions and differentials. I'm guessing 90 weight Mineral based oil???)
FIAT MR3 Grease (used in wheel bearings)
FIAT JOTA1 Grease (used in kingpins)

Thanks!

You can use off-the-shelf lubricants of the correct viscosity for everything except the manual transmission. This requires GL-1 oil, which you may be able to find in agricultural supply stores. Do not use GL-4 or similar, they will destroy the syncros. You can also use a synthetic lube specifically made for manual 'boxes; Redline MTL is one. Those of us in northern climates appreciate the lighter weight of the synthetic.
