7.5 to 8.8 Rear End Swap

[GreyHounds]

Hey all, happy new year.

For those who have swapped out the factory rear end to an 8.8 off a GT, did it just hook right up, or were there any additional considerations? I know 4.0s have the same rear brakes as the GT so I don't need to worry about tinkering with the proportioning valve to keep the brake fluid in check. Thanks.

Other than the pinion flange it is a direct swap; it's not like Ford created different mounting points for the rear end.

If you get a rear end from a 2011-14 some will have the correct flange already.
