The Robbins tops were OEM at the end of Allante' production. Robbins makes three different materials for Allante's: stayfast canvas, sunfast G canvas, and German cloth. Robbins recommends the Sunfast G top as the best of the three. It is priced between the cheaper Stayfast and more expensive German cloth. There are some aftermarket tops available, but Robbins is the way to go. The Robbins tops comes with new side tension cables and new escutcheons for the corners. The headliner is what you see from inside the car. It is sold as a separate item. I do not know if other brands of tops include this or even offer it. All we handle are Robbins tops.
