My gauge cluster in my 95 gt came out of a 95 cobra and I have no clue how accurate my tach is but I'm guessing not very since I run out of gas when I'm on 1/4 tank. So I'm thinking about getting a shift light and I'd like one that's pseudo discrete, I don't want a Mag Light hanging from my a pillar. Any recommendations? How accurate are they and how do they work? Also I'd like to mention that I really don't want an aftermarket tach, I'm trying to keep a stockish appearance.

, but its larger than the raptor and not as essy to hide. Install is the same though
Just a fwiw once you do get it installed and go to a track I recommend setting it about 2-500rpm below where you want to shift at. Depending on your reflexes that is.
Now LMR's going to get more of my money! I likey!
