This probably has been asked before but I was unable to locate a clear answer. Can someone please post pictures showing the difference between the 70 Cuda rear Valance and 71-74, I know the mounting brackets are not the same. Also am I correct in that 71-74 were the same or is there a difference in those years? Can any another year be mounted on a 70 using the 70 mounting brackets? As always thanks for any help.
