I recently bought a 1985 El Camino. It has a 305 under the hood. It came with a few modifications. The motor has a Holley 700CFM carburetor. (I know it's to big but she runs great other than the obvious issues so I don't want to change it). An Edelbrock top end, flow master exhaust and some sweet cragar rims. It looks mean sounds mean and I love it. The body is in great shape and the interior is all there. Just needs a little work. What I am needing help with is that on the instrument cluster there are some gauges missing. I want to hook them up. They are the oil pressure, battery and temp gauge. Are these difficult to install? I don't believe that anything is run under the hood for the gauges. Where could I find the gauge and all the wiring that is for them to be hooked up and how do I go about hooking them up? I also would like to turn the clock into an RPM gauge and last the car has a column shifter and I would like to install bucket seats and move the shifter to a console shift on the floor. Is it a difficult job? What would I need to accomplish this? And what would be the best shifter to use? I am not trying to make race ready or anything like that. I want it to look good, sound good and drive good. That's all. Thank you
