9" or 8

[XXBULLETSXX]

How do you tell if you have a 9 inch rear end or eight? I was once told the 9's have a more round body and the 8's have more of a oblonged body. Is that true? Any pictures and ways to identify would be very helpful.

Thanks!

Here's a good source for info that may help you tell the difference.

By the way, if it's a stock rear in a '66, it's almost certainly an 8" (unless someone swapped it). Hope that helps.

The quickest way to tell is to look at the two lower nuts holding the pumpkin in. If you can get a socket on them, it's an 8 inch, if you'll need to use an end wrench on them, it's a 9 inch.
