Looks good. Adding the screws probably helped pull them in tighter. One other problem I saw was that the originals had a weep hole at the bottom of the fins so that water wouldn't collect and freeze in the cavity. The fiberglass ones did not. When I talked to the owner of the company, he said that was an oversight and they would drill holes in the future. You might want to check on that. If water freezes in there, the fiberglass could split.
