So the angle to hold the cloth must be aluminum, correct? No steel? But we could use 7071 or 7075?
Can we interconnect the top and bottom angle pieces? We know many top tier teams do this. But is it contrary to the rules? I'm thinking a solid 5"x1"x<length> u-channel is problematic for an inspector. But perhaps if there are just some small finite number of inter-connections between the top and bottom angle that might be OK. So my last query is how much structure can there be between the top and bottom angles before it causes inspection problems.

Most of what you see behind the bumper is consider part of the mounting system for teams. Texas Torque and my team both used sheetmetal parts as part of our bumper assemblies this year that become part of the mounting system for the bumpers. Torque's are an entire c channel like you describe. We use a z- bend on our top rail and normal 1" angle on the bottom.
