I got the scoop from http://www.sledcityevents.com/fiberglass/ The quality is good but it took forever to get it and getting any updates was like pulling teeth. I have bought a hood from these guys in the past http://www.aarqualityfiberglass.com/ and it was nice, they also make the Hemi scoop. They have sold since so not sure of the quality currently.
That scoop is going to catch a ton of air. Your picture shows only two stanchions, which may not be enough to stop that thing from flapping like a duck's bill at 60 mph. Keep an eye on it.
It's actually very solid, thick glass with aluminum sheets bonded to the bottom for reinforcement. Had it up to 80 and it doesn't move, but will def keep an eye on it :icon_smi:
