This is pretty much what we are going to do. I spent some time talking to the guy at the local driveshaft shop today, and after exchanging ideas, we determined a 2 piece will be the best route to go.
Being a proper 2 piece with carrier bearing should automatically result in less vibration. On top of this, it will put a lot less stress on the CV joint.
Finding a suitable CV was the iffy part. I was considering retaining the 1350 adaptor, just as a 2 piece setup. I was hesitant to use any aftermarket CV other than GKN which is a high quality OEM supplier. He was able to find a matching CV from Powertrain Industries, which he says does not sell poor quality parts, so fingers are crossed that its a quality piece that's up for the task.
It will take a few weeks to gather the parts and get everything together, so I will report back once the driveshaft is complete and I install it.
