Also, one of those nut/stud pairs should be holding a tag.
The ratio is noted with some other numbers on that tag.
It will have the first number of the ratio, then a large blank gap, then the last two numbers of the ratio.
Something like this:
2._______79
If it says 2.79, it is an 8"...
A 9" rear would have a ratio like 2.47 or 2.75.
The Granada didn't come with any decent ratios. They are all very tall 'highway' gears. I doubt they were even available with limited slip.
However, if the ratio reads something like:
2.___L____75
The "L" in the middle is for limited slip. (aka TractionLok or Posi)
If it's a 9-inch, the ratios will be one of four that were available: 2.47, 2.50, 2.75 or 3.00:1. SOME had Traction-Lok differentials, but not many.
