Glued the old fiberglass panel to the air dam. The remaining areas will be aluminum.
Welded the first corner of the roof deck support angle steel together. Dragged it up to get an idea of final measurements for the entire frame.
I'll finish welding it up, scrape the rust off, pre-drill the holes, paint it, and then line the inside with blue skin membrane. That will keep the water away from the roof to angle steel contact area. I'll lay a bead of caulking on the roof before dropping it into final position.
