Which axle '71 Riviera

Hi guys,
Which size is the original rear axle of a '71 Riviera? Is it 8,2" ?

Thanks!

 

If you take a picture of yours and post it here, someone can ID what you have. Beyond that I don't think those came with an 8.2. It would be bigger, same as what came in full size cars.

 

Should be a 9 3/8" type "O".
