when i bought my '70 coronet 440 it was already cloned to a bee but the hood bracing was definitely already punched for the scoops and hood pins. i'm sure about the pins because mine were drilled and installed further inboard than they should have been, so when i restored the engine bay i welded the dumb looking holes shut and it's fairly obvious where the correct location is. the pins replace one of the fender bolts to the core support. there is a big hole on the front hood brace and the rubber seal already has a cutout.
