I fabbed my own using Equus gauges. I spent under $300 for everything including tachometer. They come with a twist on ring mount that makes it easy to install. You have to order one separately for the tach since it does not come with one. The speedometer uses the factory cable but it must be the earlier threaded kind. I used one from a '67 Valiant or 'Cuda. Haven't run the car yet but the temp, volt, and fuel gauge work fine after powering them up manually. After this pic was taken I have since added headlite switch, wiper switch, turn signal and hi-beam indicators. Here's a pic.
