I don't have the ducts installed yet,as I have halted all work and use of my car until I can get my house finished. I am going to try to figure out a way to put it in with the reinforcement bars that normally go in that spot.
As for my setup, I am fortunate enough to have not only the complete air cleaner assembly and all ducts, but the special A/C brackets and hoses for a L69 Camaro as well. This is important is as the LG4 stuff does not clear the L69 parts without bending it.
