I have a complete M3 shaft, but I figured out that the 2 pieces are "female" so no way to join them?
Please ask you shop how they achieved exactly.
Pictures would be better... but at least a description how to do it would be great!
I would be willing to bet that they mated them at the U-joint...it would make the most sense. Just behind the bearing at the end of the front half shaft.
