How to attach fiberglass hood

Jeez, I can't buy from them. Shipping costs.ore than the parts
That is quite common. To package and ship something like a hood, and get it to its destination unharmed is hugely expensive in today's shipping environment. Unlimited advertises truck shipping and insurance to 48 states "AS LOW AS $98" but I bet 98 bucks barely gets it across the street.
Shipping and crating is why i would try to find somebody local enough to drive to, to pick up your part.
There is/was a thread on here where a member bought a $1200 hood and it arrived damaged, and nobody, maker or shipper, would make it right.
