I bought the replacement brackets that bdosborn suggested, but I still needed to use some aluminum plates as backing on them. Hard to explain in words but here are some pics. Hopefully these will explain it better than I can.
Here is the hatch attachment, you will see the aluminum plate under the bracket. I had to use the plate here since the rib was only 3/4" wide, and the bracket would have only been screwed into 1/8" ply. The aluminum plate is screwed into the rib and the bracket is screwed into the plate:
Here is the wall attachment. Here I also used an aluminum plate, since the bolt head needed some clearance space:
Here is a shot showing the whole prop:
Here is a shot of one of the pins I purchased to help secure the prop when opened:
Hope this helps anyone wanting to install these props.
She goes in for her inspection this coming Wednesday.
