Hi Harold, having run 2 different cars (and set records with both) w/cowl hoods I understand what you are looking for, easy way to get started running your car as you develop your package. I remember seeing a steel cowl scoop somewhere, I'll try to source it and let you know (Goodmark has some). But you can run a glass hood with no troubles, just lots of Dzus fastners or hood pins.
Talk to you soon.
