The new trunktop uses guide pins (like a table leaf) to align panels together.  All mounting points and latches can be adjusted to allow for the varience inherent in each Viper.  A carpet headliner is standard.

A funtional roof scoop ($295 option) has a driver/passenger opening for cabin air flow.  Center mounting clamp also swings upward against windshield frame to prevent lift.

A total of seven mounting points hold the top firmly to the car.
