Someone should correct me if I'm wrong but it's just a 69 GTO dash in the car. From the little I know it's not even altered and I believe a dash from a 69 GTO should just slide right in.
As for getting a new one... I know Original Parts Group (opgi.com) sells new dash pads which should do the trick... But I have never ordered from them before and cant speak to their quality. Maybe do some checking online if no one else chimes in here.
I have a 70 Lemans dash in my 69. Bolted right in and plugged in to the wiring harness. Couldn't find a good 69 dash when I built my car. Any 69-72 GTO or Lemans dash should fit. It's one of those "temporary solutions and I'll change it when I find the correct part" that was 15 years ago...
