Default 8.8 rear end swap

I have an '08 v6 and I was wondering if the 8.8 rear end is a direct bolt on ( minus the flange for the driveshaft) for the v6 or are the mounting points different?

All s197 body's are the same. They use the 3 link mounting points

As Wes06 indicated, it's a direct bolt up and the only thing you'll need if the trans and DS are still the V6 base is a pinion flange (M-4851-B) to adapt the DS.

Awesome! That's what I thought but just wanted to confirm. Any ideas where I could get the whole unit? Specifically with some bigger gears?

Look in junkyards. Hopefully get lucky with the right gears you want. Otherwise you'll pay as much to swap gears as you probably did for the junkyard axle

Like mentioned all 2005 8.8 will work.

But you can not use a 8.8 from 2004 and back. The new edge/SN95 and fox bodies used a 4 link suspension that isn't compatible with the S197s. But all the gears in the differential are the same 1986-2014

Check CraigsList or Ebay and you might find a deal. The forums may turn up something as well. You may have to wait for the ideal setup or get the axle assembly and do gearing later.

I paid close to a grand for my 8.8 on fleebay. But I got springs, shocks,brakes, ebrake cables, and control arms with it. 05-13 will work.

The stock GT lower control arms are actually lighter than the V6.

I've bought a few complete 8.8 rear ends for S197's, ranging in price anywhere from $120 to $400. All about finding the right guy. The $120 one was in great shape and still in my car going strong.

If I were to try and pull one out at a junkyard, would it have to come from a gt or could I get one of the explorer or ranger rear ends?

It has to come from a Mustang - the Explorer and Ranger rear ends have leaf springs for mounting and not the Mustang 3 link; plus the Explorer is a different width.

You can use a rear end from any Mustang 2011 to 2014 and any GT rear end 2005 to 2010. Some of the 2011-2014 rear ends will have the correct flange on them for your V6 - won't know until you pull the rear end and check. I never figured out what the combination of options is that has some with the correct flange.
