If your main concern is the gauges, then check out New Vintage. I recently installed a set in my son's 67 Camaro. They bolt right into the stock gauge carrier and provide a total of 6 gauges (3 gauges per gauge)

If you are talking overall dash layout, then this won't help, but I do have a 4th gen dash I'm looking to get rid of!
