1963-64 Tail lights
Before forging ahead, run a cost analysis to see what you'd have to charge for lenses.
David Azzopardi in Australia already makes very good quality tail light, reverse light, and front turn signal lenses for (at least) '60-'69 Valiants and Barracudas and '63-'73 Darts, for affordable money. He's usually slow to respond to enquiries, but he does very craftsmanlike work; his lenses are real nice.
Might want to start in with parts that
can't be had in good quality and/or for reasonable money and/or at all, like headlight rings for '63-'64 Dart and '63-'65 Valiant/Barracuda.
