K2500 rear axle identification

[Kirth Gersen]

I've been searching for a very low mileage 2004-2006 K2500 Suburban for months, without much luck.
A photo of one seller's Suburban was missing the center lug nut covers on both rear wheels (but front wheel covers were present).
On pic below, is this a stock rear axle?
I've never looked at one, before.

looks like a 14 bolt full floating rear end to me. aka stock for a 2500 or 3500.

the center cap might not have fit over the axle there, when i did my wheels on my 03 hd 2500,
(same rear) i had to find a pair of deeper center caps for the back wheels.
