You're very likely never going to find one, and this is a trivial repair.
Glue it back together from the back, bridge the traces with solder, 5 minute job.

Hi there

I have had the same issue during transport ( 800 miles trip) the backdoor get loose , door lock bumped into the circuit board and brake it ,door is worn lower side , it was poorly fixed with some wood screws . I have repaired the circuit board tough but now I am after the Manual with the targets adjustments information if somebody did a scan please Help . I do have the schematic find it online but no manual on the web , so anyone if have the Wild kingdom Manual please Help ! I am now at the resurrection start , game do start but do not register shoots and Charlie do not shoot either . Game was collected without the 8 track tape, I have had to buy an 8 track recorder and then to record the tape, mp3 was found on Clay's page so the the background music is there
