That one is pretty obviously a totally custom made mold. Looks cool, but that won't be what you get by just plopping a cowl scoop on a stock Grabber hood.
I think I will try to sell my grabber hood and buy a fiberglass hood with the scoop already on it. It will most likely cost more than putting a scoop on my grabber hood myself, but I believe the return will be worth it.
Why don't you talk nice to Maverick Man? He already makes a killer cowl hood and is developing a Grabber hood. I bet he could merge the two together for you... and in carbon fiber no less. CF requires no fitting at all like fiberglass parts. It is pretty as-is as well, so you could put it on and ride. Then paint it when you got around to it.
