Often with a little carful soldering, and making up a sub wiring harness to bypass some of the broken pins, one can keep the existing board.
The photo below is of a 1967 Dart’s circuit board. I had to bypass a few pins that supplied gas gage, temperature gage, and a few other devices I have now forgotten. As you can see there are orange, yellow, green, and blue wires that have been grafted to the board, and terminate in a new multiple socket connector that replaced the original six pin connector. The car’s harness was modified to accept the new six way connector so that installation of the gage cluster is an easy plug & play.
