Default Rear End Upgrade On '13 V6 Coupe Automatic

I want to upgrade my rear end to 3.73. I'm new at this forum and this is my first Mustang. I need help on part #s and where to buy cheap. They came with 8.8" Rear Gears from the factory, right? I found a Ford Racing kit at eBay listed for $248.33 w/ free shipping, ford racing part #M-4209-88331 and #M-4210-B2. Is this the one for my car?

Starting in 2011 model year all Mustangs come with the 8.8" rear end.

That kit should have everything you need. Starting in the 2010 model year the pinion bearing was changed but they advertise that it has everything.
