Ph3 headlights in ph2

[Moh]

I'm thinking of putting phase 3 headlights in my phase 2. After looking at a few threads I've gathered that the headlight adjuster motors are different. Does this mean I have to take the adjuster off my ph2 light and put them onto the ph3 ones? If so how hard is this..

Also due to the phase 3 lights using H7 bulbs will the full beam work simultaneously with the dipped beam? or will I need a phase 3 stalk as someone has briefly touched upon this on a different forum but not gave much info.
