Mark,
The ZF diff that you have in your car and new Camaro's use, needs the super-strength stub shafts that G-Force builds for the diff. You not only pick up a near indestructible stub shaft, you also get the ability to use the giant Porsche 930 CV joints. No one else that I know of offers this for the ZF diff.
In your case instead of asking for the Ford 8.8 versions you want to ask for the corresponding new Camaro axle package. It will come with super duty stub shafts, the upgraded giant Porsche 930 CV joints and extraordinarily strong axle half shafts. Because our cars have a different width rear axle assembly than a Camaro you will need ask the G-Force guys how they want you to measure the width back there and they will build the half shafts to fit your car.
Believe me it is worth the effort. You already had one whoops, you don't need another. Under power this type of failure con crash the car. This is the short way home to fix the shortcoming. Here is the link =>
