Suggestions for 6-bow headliner '70 Duster

Classic probably get's theirs from Legendary. and doesn't stock much in their own warehouse if anything. If they include the sail panels as a "kit" I can bet the price is higher than the headliner alone. That's marketing. Bundling is what they do.
Once I got through to Classic, he did say they were "included" at the $119 price but the pic on the website looks the same as Legendary. They say they are made from "Acme Interior". Never heard of it. Legendary sells the sail panel for $97 alone. I can't justify that cost in a car that isn't of show quality. They make nice stuff, though. I got the entire interior from them in 2012 when I restored my 1970 Roadrunner.
