I have an 87 caprice. The dash only has an 85mph speedo with a fuel level gauge. Im swapping in a t-56 transmission so I need a tach. What I want to do is pull out the gauge pod/cluster unit and make some sort of sheetmetal? gauge panel and cut out some holes to put in an aftermarket speedo,tach, fuel and a few other gauges so I can keep an eye on all the vitals. My vehicle is no longer computer controlled so I dont need all the dummy lights it has. Any suggestions on how to get started and if I should use sheet metal or something else. I will have to add my own lights for turn signals and hi beams so I know when they are on. If sheetmetal is preferred would it be wise to rubber mount it to keep vibrations down?

Thanks and I hope I didnt confuse anyone.
