DIY 03 G35 Coupe 5AT to 07 G35S 5AT differential swap
#48
If it looks like the 2007 I've posted and if you are able to swap the flange and the dust cover and cut the pinion shaft, YES it will fit 100%.
The only special tools I needed were a puller for the flange and an angle grinder with a cutting wheel.
It's currently installed under my 2003 G35 5AT. I will take pictures tonight since my car is in the garage.

To find one I'm not sure, since you're in a big city call a couple junkyards and probably that you'll be lucky. I've found mine on "Lespac.com" in Sherbrooke. I recently saw a 370Z complete for parts but I'm not sure if the seller want to part out. In the past I also saw 3.5 from a manual but not sure if that's what you looking for.
I will also check for the CC cause it may still works on speed below 80mph according to what I've read.
I can also give you my MPG but I did not record it before the swap, so it may be of no great value since each car/driver is different.
