1971 demon headliner bows

I have the 3 hole slots in 5 places. I have 6 bows and new headliner but my bows are apparently for a duster and dont have the right ends on them. I have an early 71
Got it......Straight ends that fit into the little cups. Saw those on a 1970 Duster.

Sorry, I thought that you were starting from scratch. Just giving you another option.

Good luck.
