PIC with Quest for info...

[Bullit]

Can ANYONE give me any info on the diff? I was hoping to get just general info from this pic.. (yes, I know it's been apart and it looks rusty already). From the stampings and numbers, Is there anything out of the ordinary?
thanks,
Bullit

its a nine inch case. thats all i can tel. the ratio numbers will be on the tag that isnt there anymore. its not a nodular case. because it doesnt have a N cast into the case. the date code reads 6th day of the 10 month of 2?

While I do my Pick-Yard travels, what should I be looking for that jumps out and says "POSI-UNIT" to me. TONS of trucks there (and Bronco's too) that might have one. I know about the "high nodular iron" marking but have not seen one in person and I keep looking. Is there a "visual Que" I can see or particular vehicles I should focus on?
Thanks Guys!,
