i have a 71 charger with a tach on the hood and was wondering if anyone has any info on it i have a offer to buy the car and was wondering if this made it more valueble any info would be great

 

fairly common back in the day. Some came from the factory and some were aftermarket and some were dealer installed. Depends at what point it was installed. Shouldn't raise the value all that much but they are cool. Not sure if the factory installed these in 1971.

 

i do not believe that was a factory thing
