I would consider just 3D printing the 14-segment baffles and then use SMD LEDs behind them rather than try to source the exact precise size and color of display.
When we designed the replacements for the real DeLorean 3D printing wasn't that great, and we needed a lot of sets. Doing it again for a small run? Definitely the best way in 2025.
