With my V8 the light-width regulation on one side no longer works

Now my question:
Can you change the pressure box on the headlight without having to expand it?
She seems to have disassembled it. Pressure comes on, other side funks. The reflector is also loose at the defective side. Otherwise, all connections look fine (the one to the can), only you can move the complete mechanics back and forth. Not healing. Take it that it has disassembled the can inside. Yes, the age.
Since I have just overtaken the SW (the from the V6) from the 80s I know that one can expand the adjustment motors (the have motors ). Also in built-in condition .
Is this possible with the V8 with the pressure box?
