What resistor are you using to fix an 88 tpi tach? Where? link? for the part
i appreciate it

Piece Of Resistance
It depends on how far the other components have changed from their specifications.
There is circuitry in the dash near the tach.
It’s contained on a small plug-in PCB or integrated in the main board.
On or near the PCB you’ll see a capacitor, replace it.
Also on the PCB you’ll see a resistor chip.
Desolder pins 4 & 10.
Use a 500K potentiometer.
Solder it across traces 4 & 10.
Move the potentiometer to half way.
Start the engine and compare the tach reading with a test equipment quality tach.
Dial it in, unsolder the potentiometer, measure it and install a matching resistor.
