This may be a dumb question, but I'd like to know if there is any interchangeability with Cutlass hoods between 2 door and 4 door/wagon. Are '78-'80 Cutlass hoods all the same? Are Cutlass hoods different between 2 door and 4 door/wagon from '81-'88? Also, is there any interchange between Buick Century/Regal hoods and Cutlass hoods? Thanks in advance.
