Anyone who has been around me for a little while knows I like to be able to see what the car is doing. Particularly considering that work I am putting into this I want to be able to monitor it's behavior so that if something starts to go wrong I can start taking it easy or something to help it along. At this stage I am looking to add a voltmeter, tacho, oil pressure & probably manifold vacuum gauges. I may also add an oil temp gauge, but that can happen later; Particularly if I start working this a bit harder.
