I was just wondering if the G80 was a 10.5" or a 11.5" rear end? and if the front dif is a 9.25? I am looking at gears and I just want to be sure of the sizes. Thanks Jon

The rear is an 11.5





Not sure about the front but 9.25 or 9.5 sounds about right

G80 just indicates the locker option. That RPO does not indicate what axle is used. That same RPO is used all the way from the baby 10 bolts up to the 11.5" and probably bigger rear axles. All the diesels and big blocks have the 11.5" rear and the 9.25" front.
