I have a tach/speedo assembly but the back of the tach has a switch to change from v8-v6. Mine is broken off and doesn't specify what way is what. Does anyone know if left is v8 or right is v8? I can toss up a picture later to help show what Im talking about. thanks.

Its a factory gauge cluster from a LeMans or Grand Prix with the tach and spedometer instead of the clock and spedometer. I'll try and post up a pic later tonight. Computer crapped out on me so I'm not on much.
