Bonding Fiberglass scoop to a steel hood

I have a stock steel hood on my '67 dart, and i bought a bolt-on scoop 6-pack for it. Although its bolt on, I still want to bond the hood on somehow to give the area a "smooth transition" if that makes sense.

And once I bond it, I will be painting it Hot rod(satin) black. I know that i cant use bondo, because this will just crack. but what should I use to bond my scoop onto my hood??

has anyone done this? do u ahve pics of your completed hood?

thanks FABO!
