Factory tachometers and alternatives

[mikep]

Factory tachs are like Brittney Spears... A useless decoration. I like a tach to tell me one thing and that is when I am about to overrev my engine so I can stop what I am doing namely pushing on the gas pedal. Factory tachs go to 5500 rpm and 5500 rpm isnt what I would call close to overreving. Who here has gone the extra distance and installed a real tachometer that looks close in ppearance to the remainder of the gauges on the cluster ? What did you have to do to get it in htere and do you have pictures of the process.
