It's dead simple to replace the floppy circuit sheet but me , I prefer to take the whole thing carefully apart and hand polish the contacts where the MPC goes , this removes 40 + years or built up oxidization & makes the gauges more accurate plus I always clean out the dust and spiders etc. so they illuminate better @ night .
90 % of the time , careful cleaning will get the entire dash back to AS - NEW working condition .
The clear face panel cleans up easily with Meguiar's plastic polish too , all the grime & overspray comes right off .
I'm going to look up some more multi - syllable words now......
