Okay. I'm about to swap out my posi-disc 9 bolt for a posi-disc 10 bolt. Is there any special knowledge that I need *before* I start this swap, or is it essentially bolt in?

Thanks,
Willie C.

Its a direct bolt in. I've swapped 10-bolt to 9-bolt on mine and my dad's car twice, and its fairly simple and straight-forward. Good luck.

When I did mine I didn't even take off the calipers. Unhook the brake hose going to the diff, unbolt the calipers and drop the diff out Install the new diff and reconnect everything. I had new brake lines already on the new diff so it was just a matter of reconnecting the flex hose and rebolting on the calipers. That way I didn't have to worry about the park brake cables.
