Message It helps a lot.
I'm going to raise the transmission with polyurethane puck inserted b/w the metal and the rubber of the transmission mount to achieve 0° and give it a try.
I have also now some concerns about the quality of the CB70 sold by the australian sellers. I have now a new OEM in my hand, and seems there're more tolerance in the welding locations on the CB70 .... meaning the CB70 is not perfectly straight or aligned.

I fitted back with the marks I did before separating the 2 pieces of the driveshaft (I had only removed the first part from the transmission to change the CB keeping the second attached to the diff).
Yesterday, I checked again how the yokes of each piece are oriented and I discovered the first shaft is not correct (opposite yokes of the first piece are 90° phased in my case, pics 2&3 below) comparing to the literature ! but it was like this since I got the car in 2004 !
Maybe it's no so important when you carefully respect the 0° angle b/w the transmission and the CB .... I assume I had more or less 0° angle with my old sagged CB ...

I didn't succeed to find on the web a pic of a 2+2 TT driveshaft, maybe they are like this from the factory.

Last pic show my trans mount gap, I have about 4-5mm b/w the metal and the rubber, are OEM supposed to sag so much normally !?
