I know exactly what you wanted. You ask me for posi fluid on a Mopar and I'll tell you you're in the wrong place.
and it's whale sperm, not sperm whale oil. they used to actually use whale sperm as an lubricant. smelled like hell and you didn't want to get any on you.
Hasn't been used since we started hugging trees and saving whales.
But that stuff worked great!
