No broadcast sheet was ever found with my car. The FSM does indicate what engines that came with what transmission was married up to a specific carb. All you have to know is what engine/tranny combo were available with your particular year/make/model and you will know what carburetor belongs on the car for a specific combo. That is on your fender tag. Broadcast sheets are nice to have but you don't need them to find that out. Various sources on the web suggest that 1971 Roadrunners had more Carters in them than Holleys and the exceptions to that rule I've already mentioned in this thread. My car originally came with a Carter AVS because it came standard with a 383 and 727 auto trans. The FSM backs that up. The Air Grabber hood though, is a completely different story.
