Heres my attempt and creating a hood not available from any of the vendors. Its designed to provide a path for the air entering through the radiator to easily exit up and over the engine. It was a ton of hours, very messy and I will probably never attempt it again...;D
Started with an old K Bar S hood
Some kids project foam board
Sliced up some louvers
Epoxied to the old hood
Multiple layers of fiberglass mesh and resin
Sanded, filled and formed for hours and hours
Painted up!
Blacked out the louvers. I am really pleased with the results.
