66 Dart 270 Convertible

Welcome! Looks like you have good info on how the do the dash pad. I would only add that you should do everything else it might need at the same time. Such as: dash bulbs, tighten all the gauge nuts, lube the speedo cable, change the wiper post seals, heater core, wiring work, etc. Pretty much everything you can think of while the dash is apart. If it needs rust repair, windshield, or gasket, nows the time to do that too.
