Anyone built a 6 pack hood plenum?

We built one for the AAR hinged 6-Pack hold on the Demon in my avatar.
I will try to get pics this upcoming weekend.
I built one from aluminum & attached it to the underside of hood with panel adhesive, the type for installing auto body panels.
It has been installed for 4-years now. No signs of cracking or coming loose.
I just made a simple cardboard template & transferred it to the aluminum.
