I have a 92 rs with the v6 in it. In the next month or two I am swapping it out for a 350. I need to know what resistor,cap,ect.. (little black chip) to replace mine with so the tach will work with the V8. I have read the post were people have fix the 85-89 tach but none with the 90-92 tachs. Please help cus a used 145 cluster is kinda expensive.
