I had Instrument Specialties repaint the dash frame & restore the tach from my 68 Charger two years ago. I removed everything and they repainted the dash frame. Excellent work, great communication and turn around was not bad at all. It depends on how much work you want them to perform. A complete dash rebuild is a lot of work for sure.
Top quality work takes time, a lot of it. There must be a reason they are so busy and their work is in many of the top cars in the country.
P.S. I am not affiliated with Instrument Specialties in any way other than being a very satisfied customer.
