the belly pan as it is was not very sturdy. it's always got caught in the wind and the choroplasr melted near the transmission and engine. therefore I decided to build a frame out of aluminum to make it more stable.
the frame is made out of aluminum screen door frame found at home depot. it is sturdy because of the box shape, lightweight, and cheap.
5/16 in. x 3/4 in. x 84 in. Aluminum Screen Frame-3021650 at The Home Depot
the main goal was to use pre existing holes and not drill into the body.
First, I made 4 horizontal braces. I used pop toggles from home depot to drill into the pre existing holes that are originally for the side skirts
Front of the car brace. It's attached to existing tow hooks
