Is this rare? a stock /6 with a 8 1/4 rear w/3.21 gears?

Yes, this is a continuation of my other post with a slightly different topic. I just hoped to get other opinions on the issue with out the clutter. Is this stock or has it been replaced?

This is how I bought it. It's a California car with 2 female owners. I have all the records in a folder (That I know of), and it doesn't say anything about the rear end being replaced. Maybe in a accident??

Is this unheard of? Was this an option??

I am putting in a 360 so this works perfect for me! To make this a Sure Grip Posi would I just need a carrier then right??

Thanks!
