From what I remember, it is not a direct swap. You need an adapter of some sort to do it, but it can be done. Sorry I could not be more help.

Spline to transmission on the 05 was different than 06 up. Just need to change that.

The A6 uses a 30 spline.

I'm no expert but no, you can't. The experts will chime in at some point but here's a prior discussion to start your thinking:

Pretty sure the manual diff s are the same spline count. Z06 and auto diff s are 30 spline.

Correct. Isn't that what I said? Or am I missing something? He wants to swap in an A6 diff. I don't want to give bad info or cause confusion.

I know I’m bringing this thread back from the dead but does anyone still make those diff mounts to put a C5 z06 differential in an 05’ C6? I saw somebody’s user name on here (Stanger383 I believe) and I tried to send him a personal message but I’m new to the forum so I think that might be unavailable for me right now because I’m so new. I don’t know if anyone could potentially reach out to him and give him my username. Or if he wanted my phone number or personal email and someone would be generous enough to pass that along.. My differential is making some sporadic wines and after I changed the fluid, it straight up looked like silver paint lol
