After the hood was painted I attached the seal with the provided pins. BTW I purchased an OEM replacement for the seal and the washers. I left the originals attached to the factory hood in case I ever wanted to sell or reinstall it.
Here is where the Seibon hood provided for the attachment of the washer hose clips:

Here are the washer hose clips:

The clips are designed to fit into a square hole. Unfortunately I couldn't find my square drill bit and Home Depot was out so I had to find another way to attach them. After scheming for a couple of weeks on how to cleanly install the clips and coming up with nothing that satisfied my standards of excellence, I just happened to find a package of adhesive wire tie clips on my workbench. The bells started ringing and the lights started flashing and I realized it was the perfect way to attach the clips.
I'll add a pic tomorrow for clarity.
