hello i have an 89 that used to be a 4 cylinder that is now a carbed v8. the only gauges that work right is the amp gauge,the speedo and the fuel gauge sometimes. what suggestions does anybody have to replace the old gauge pod.i was thinking maybe getting some diamond plate and putting and aftermarket speedo, with a fuel gauge and and amperage gauge. i already have a water temp and oil psi gauge where the ac knobs go. and a small tach also there too but i was thinking i should get a big aftermarket tach to go next to the speedo on the diamond plate. what other ideas does anybody have and what problem will i run into, beside the sun's reflection in my eyes from the diamond plate.
