what to look for in a dana 60??

That is just beautiful ......I can almost smell the 90 weight through the pic.

90 Weight has an underappreciated aroma. Seems to be kinda strong in an enclosed garage. But its gorgeous when clean and on something like Dana gears.

That's kinda funny. It does to me too. Sorta like a dog sniffing chewing tobacco, he shakes his head and backs off yet keeps coming back. An alluring pungency.
