1966 Valiant interior panels....where to buy new?

If you have your original panels and they are in reasonable shape, you might contact Legendary Interiors and see if they might want to use yours as a pattern for reproducing them. Then they could add them to their catalog. But, 1966 Valiant 2 door sedan parts may not be a big seller. It's worth a shot.

I've done this with other parts in the past and ended up with reproduced parts for free, or at a good discount.
