The total ideal difference should be less than 1 degreee, and every side should be less than 3 degree. Your diff is ok, you have to correct the transmission angle.
You have to raise the gearbox, right? You should put a shim between the transmission support and its plate.
Keep in mind that rising the gearbox will change the diff angle too.
