I know there is a company out there that sells new analog gauges with a wiring harness installed on a replacement panel that looks like the factory orig. It's not Covan, and it's not Dakota, does anyone have a name to this company?

They make a dash insert for the 64-65 that is engine turned and built to your specs.
