Fastharry,
I'm not sure if anyone answered your earlier question about the ease of removing the 710 diffs that you had a while ago. I didn't see an answer on the first readthrough. This is what I have observed.
In the rear, you must remove the six screws from the bearing caps (remember: two are behind through the shock tower) and the two back screws beneath the chassis. This allows you to pull the rear "cover" completely off to expose the area above the diff to pull it straight out. All in all, eight screws and pull it out.
In the front, you must remove the four screws from the bearing caps (which are attached to the shock tower) and unscrew one shock. Then, pop one ball cup from the steering knuckle to allow the knuckle to turn far enough to remove one dogbone from the outdrive. The front axle then comes out at an angle. All in all, five screws and one ball cup.
It is basically as easy to remove the diffs as it is in a Tc3.
