There are quite a few cowl-hood options other there, and they require the replacement of the entire hood. There are some bolt on cowl-hood scoops... but I don't believe that is what you are looking for.
How much clearance do you need? What is your budget?
I want (need) a new hood...I have some ugly **** popping out on my hood under flouresant lights.:nuts: I plan on wet sanding it in the spring but if the **** doesnt come out I think I will buy the high rise 84 hood.. I also was thinking about Carbon Fiber hood!:excited:
