I have a 1971 383 Cuda rallye hood Nov.5,1970 build date and it has crush zones.I also have a 1971 Shaker Cuda that has the same Sched. build date and it has crush zones. I have never seen a Shaker hood with crush zones that was built in Nov or Dec. of 1970, the 1971 production year. That does not mean they are not out there.
