I have not seen any paper work on this Jan.1st.1970 date for any changes. There is paper work on when the Shaker Hood was to come back into production but I do not have that either.

Owners of 1970 E Bodies that were built between Oct.31, 1969 and the end of production in July 1970 would post the build date and the type of hood and if it has crush zones or not, then all might see a pattern. I say all E Bodies because I wonder if the same thing was going on with the Cuda as with the Challenger with ALL types of hoods and if any 1970 Cudas got the Crush Zone Hoods. There are early 1971 Shaker Hooded Cudas that have the None Crush Zone Shaker Hoods. This could be because of left over product from the 1970 build. Did all the Plymouths get the none crush zone hoods in early production, lets say before Oct.31 1970.
