Standard To Rallye Dash

I had to read a bit to learn that this car / original dash was 72 model Dart Scamp. Readers should note that a 73 and up climate controller will not fit a rally dash.
As for working with plastics,,, it is what it is. If you had started with OEM bezel you would have found that removing and reinstalling attached pieces, especially the 2 green lenses, to be the same, use glue? what type glue? challenge.
I assume the new reproduction bezel would have a nice straight brim line at the dash pad. OEM bezels are often wavy along there. A flaw that might not be noticed until installed. The factories metal heat shielding piece did help but after 50 years,,, we find there wasn't enough fasteners in it.
One more note... Any gauge screens are supposed to be a very flat finish. Glossy can cause glares. In this case, blue tint diffusers and all, there isn't enough light for screen finish to matter much.
