I need hood scoop template for a Dodge Dart sport

I like that option. Thank you. The scoop I'll be using has an internal flange though, so no fiberglass boss like the one above. I'd still like to use some type of mechanical fastener, but it seems like whatever fastener that used needs to be positively attached to the flange or tightening it on the underside may be challenging.

Does the flange on those studs cause the scoop to not sit tight against the hood?
The boss height needs to be slightly low or at least have a recess the flange can tuck into...

If I were attempting to attach a scoop I would form bosses on the underside of the scoop with fiberglass resin with some glass fibers in the mix for added strength... Hit the areas you plan to create the bosses with some 40 grit to give the resin something to grab ahold of, probably should lay a 2x2 piece of glass mat on the back of the scoop to spread the contact..
