I have been advertising in the Driveline for a complete original shroud for my 66 for two years - mostly due to the lack of information about how the factory did it - as opposed to what the AIM and JG say. Everyone I asked gave me a different description. There aren't enough BB with A-C cars to provide a photo of an original shroud with an extension. If you locate an original at a show, take lots of pictures, and sell me some. I haven't seen an original in the last twelve years. Lots of repops and retrofit GM parts, but no originals. - Dave
