I may have designed a good fix for hidden front bonnet mounts. It will work with either a tilt front end or a regular opening hood.
I decided to not go for a tilt front so I am using stock hinges. I redid my front end lower valance and removed the air box on the backside of the grille opening.
I also eliminated the stock hood latching system. At first I was going to use Dzus Fasteners on the lower valance. It did not look like it was going to work without a lot of additional fabrication. I looked at the ways others have strapped or latched the lower bonnet wings. I wanted to pull them in close so I am going inside the wheel well and attaching to the inside of the bonnet wing at or near the bottom. It opens and closes and doesn't interfere with the side.
Mounted what was basically one part of the bracket so we could locate the bracket to the hole.

Hanging loose at this point. I am showing both sides.

Tacked it to the part of the bracket that was mount to the lower wings. No picture for the part attached to the wing prior to spotting them together.

Now the 2 parts are mated together and the gap was filled.
I would show you the finish bonnet but there is nothing to see. What really happened is that I forgot to get a shot before I loaded it in an
enclosed trailer. Should get it out later this week and will post them. What is nice is the fact that there is not anyway the bonnet can open at any speed. It pulls the wings in nice and tight and helps sets the gaps on the bonnet.

The only issue is having to undo the Dzus fastener from inside the wheel well. With stock wheels it should not be an issue. Opening the bonnet will always require a screwdriver.
