Couple pictures of a local car I have access to - CSX3254. Currently for sale for 1.3M
You'll find it easier to mold new edges in place than trying to patch in strips from Hurricane, if they'll do it. They are pretty backed up on fiberglass work. Take some cardboard, cover with aluminum foil and tape to your existing opening, forming a backup for the fiberglass you add to the body and partial lip you have. When done, strip out the cardboard and continue the build up till you get it where you want.
Hope these help.
