Hey ? about fiberglass hoods what to look for?

Tough to say since you can't line it up to the car, but the obvious: cracks, dings, dents, uneven sides, etc.

Coming from Cervini's, though, I don't think you have anything to worry about.
 
yea, i picked up my hood from Mustangs Unlimited. I think ABC Exclusive is their supplier, and they're great as well. $20 in taxes was much better than shipping charges!
