Welcome!
Nice vehicle.
I can see why you'd like to make the cluster swap - I'll shoot you a PM.
With the shift knob, there may be a more efficient (but expensive) route of installing the Polestar performance part.
It's not the actual shifter found in the later model Polestar variants (with the clear & blue backlighting)
But a better looking version than what you've got
You'll need to check with volvo to see if they have a polestar performance part for your VIN or look for a 2013 RHD shift knob
