So I put back together my center console and what better time to rip something else apart. 😂 I pulled the gauge cluster to check out the lights and tach. I bought a new tach board from West Coast. First photo is the original then the new one. It has a pot to fine tune it but came tuned for an 88 4cyl. Also has a diagnostic led... since all but 3 bulbs were blown I didn’t finish reinstalling it last night.
