8.8 swap

I am picking up and 8.8 (3.73 lsd) tomorrow and trying to decide whether or not to cut it down. I am building a 72 dart with a pro touring vibe. I plan on running late model mustang 17x9s in the rear. So I have 2 questions for those of you in the know.
1. If I run the stock length axle will it work with my wheel combo, and fit the wheel well? ( also installing dr. Diff offset shackles)

2. Will the offset of the pinion cause any issues in stock length?

Thanks in advance for the help!
