Dart Sport/Duster headliner

I find it odd that Legendary shot down the abs headliners with out giving you an option. I will be buying one soon because mine is sagging and can't be recovered. I have installed my own cloth headliners before without a problem but the fact mine didn't have one makes me want to stay with the ridged style, this way i don't have to do any major alterations, gezz how bad can they be?
