Go-wing Spoiler on 70s Valiant

This is on the four door? I have pictures of one on a '68 two door sedan, they're basically the same right?

Do eet!!!

Sorry to bring this back from the dead. I have a 2dr ‘68 and someone locally is selling a rear wing identical to that which keeps tempting me. In my head it would look even better with the bumpers shaved a bit on the inner lip and remounted to sit flush with the body shape. I have a spare front and rear, could be a fun thing to try.

Would love to know what/where the front duck bill came from, reminds me of what was fitted to a mk1 Golf (Rabbit) GTI
