But 3.5 shouldn't be a big deal... $200 - $250 maybe? Whats the shop's hourly rate?...

If he could get his hands on an G35 input flange (or whatever it's called), he could probably do that himself and then just ask the mechanic to do the actual swap.
I'm actually looking around for a spare diff that I can raid the input flange, axles and rear diff cover from.

0- Drain oil from "old" diff ~5-10 min.
1- disconnect driving shaft (four bolts) 10 min.
2- disconnect both axles (twelve bolts) 30 min.
3- disconnect breathing tube and abs sensors ~ 2 min.
4- remove pumpkin (two bolts + 1 nut) 10 min.
5- remove and pull flange from "old" diff (1 nut + puller) 5 min
6- remove and pull flange from "new" diff (1 nut + puller) 5 min
7- swap the "dust cover". It is kind of press fit and quite simple to swap 5-10 min
8- install the 03 flange on the "new" diff (one bolt) 5 min
9- cut input shaft (angle grinder with cutting wheel) 2 min
10- reinstall the new diff following steps 4,3,2,1 ~ 52 min
11- put oil in the new diff 10 min
12- DRIVE !!!
I did took my time so as you can see it should take at most 2.5 hours (175-200$).
You can also note that swapping flanges is really easy 15 minutes at most and that's including time to figure how to swap the dust covers.
Don't forget to give your comments once done
