Rear window blinds (venetians) - 60-62 Valiant 61-62 Lancer

While these are available in Australia for the Series R and Series S Valiants, has anyone found a source for these cool blinds in North America?

Rear shades (and front Fulton visors) are very common accessories for vintage cars of all types in Australia. Might be an unusual option at your next car show if we could find one here.

Thanks, Lancer Dave
