Now I appreciate I shouldn't touch turbos

but I'm going to anyway and would appreciate some assistance.....
Here we have a low mileage BV39, the main body needs to be clocked nearly 180 degrees and then the cold scroll(?) need to return to it original position

First off, take it apart, a single locating pin should make it fairly easy to relocate the body, but the vanes present a challenge

Ideally I'd like to move the vane marked with a white dot over to the vacant space or rotate the vane assembly the required amount

I've no idea how it is assembled and what solution would be workable until I get the thing apart.
Which is where I got stuck last night, (actually it was 2am this morning)

I had a few prods at the assembly and gave it a few taps with a punch but mechanical sensitivity and the time of day thankfully stopped me from reaching for the big hammer and belting it to death.
What is the attack mode from here? Can I tap that ring out with a punch, do I need to make a tool with a pin on it? Does that assembly turn left or right?
Or should I leave the vane assembly well alone and just move the actuator instead?
