Cryengine Sandbox Tachometer And Speedometer

Hello We need to get working Tachometer and Speedometer for a car in latest Cryengine Sandbox. You can find how to make it using existing features of Sandbox, or create your own. Car should be able to be set up with different gears ratio and it should shift gears up/down during acceleration/decceleration, making rpm higher/lower and so on. Also it should be possible to shift gear up/down manually, so car should act like in any other racing game. Not like now - only accelerating/deccelerating without gears. Sandbox has some of these features, they just needs to be set up. No pre-pay or initial milestone, bid only if you can do it.
