Anyone out there know where I could possibly find another broadcast sheet or extra info on my 1971 roadrunner?

I tried contacting galen govier a year or so back and it took months for me to just get an email saying what his rates are for looking up info (jacka**). The Chrysler historical museum archives told me a long while back that there was a fire that took out some of the archives and weren't sure if they had any punch cards? for 1971. Anyone know where else to look? I'm going to try and contact the chrysler museum again and see what I can dig up. The most they offered last time were brochures and owner manuals.
