Not sure if that panel fits a 70 - best to check for fitment with Classic Dash. I bought the gauges separately from Speedhut. Each gauge came with everything it needs - the Speedo is GPS, so the GPS antenna sits on the dash (and works perfectly). As far as wiring, I just bundled up all of the gauge panel wiring and used a couple of 6 pin Molex connectors for easy connection of the gauge panel to the dash/car wiring. Tedious, but straightforward.
