Your V6 car will have the 7.5 rear end. You can not put 8.8 parts in a 7.5 rear end. You need to get a complete 8.8 rear end out of a GT.
The drive shaft doesn't matter.
Building a rear end is far from a bolt in job. You MUST know how to set the pinion depth, bearing preload and backlash to get the correct contact pattern. You also MUST know how to read the pattern so that you will know what adjustments need to be made to the pinion depth and backlash.
