1998 Tach
Mike, I have the same problem, only one tach working, and your right. That part number is like gold. However I just replaced them with a tach from "Summit Racing" part number SUM-G2969. $109.00 each, a perfect fit and they look great in the dash. They have only been in for a day, so I'll post later and let you know if I blown any fuses or if they stop working. But if these continue to operate correctly, I plan on changing the other gauges to match. Good Luck.
