ASI Radio PCB and potentiometer

[GDTDMC12]

Following damage sustained to my ASI Radio during shipping (for general refurbishment), despite great care taken with the packing, I am looking for the following part(s). If anyone can supply or know where to obtain these parts I would be very grateful for the information. I've looked at a similar BMW 1982 ASI radio but I'm told the similar part is not compatible so it seems I do need the DeLorean ASI radio part.

This is what happened, see the bent stems to which the knobs attach:


The right hand one has been repaired:


But the left hand one is beyond repair:


I am therefore looking for the left hand PCB and potentiometer as shown in the following three images:






Thanks in advance to anyone who can help.
