[silverback]

rich we bend 0.50 aluminum 1'' thick for the louver and two inches for the side of the car.We either rivit it to the louver or use stainless screws passing threw the back of the louver into the 90 degree bracket and then fiberglass it to the car. The screws are nicer to use because we install thread certs into the bracket wich allows us to remove it when needed. Hope that helps............................mahlon
