I have copies of a set of factory Technical Service Bulletins for a 71 Challenger Electric Sunroof. 12 pages in all and has exploded views and diagrams to show how to maintain and repair the sunroof and also shows the how to's of manually operating it as well.I am not sure but I would think this would be the same for a 70 sunroof car as well, not sure though. If anyone is interested please drop me an email. Thanx
