Just installed one today in a 70 challenger i am no pro but it went in easy. Just lay it out in sun a few hours before makes it easy to pull.Start at #4 bow pull to front, clip in place pull sides and clip in place. Tip go to a office supply store buy binder clips med size 15 for $3.50 use them to hold everything in place until you get the headliner where you want it then glue the edges. Take your time and it will turn out great. If you have any wrinkles heat with hair dryer and work them out before you glue.The rear sail panel area is the last part you need work.
