lol i know thats where it is but its hard to tell in pic how curved it is. i dont see why you can just cut a nice hole with a hole saw and use those grommets. if that ring is metal you can bang it into any shape you want so curved area shouldnt really matter to much. only thing is you will have either rivits or screws showing under the car in the tunnel. if you can live with that i think it would work. another thing to think about is if you have to pass a connector through it you may want to cut your holes and everything and maybe cut the wires and just pass the thin wires through the grommet connect it into the trans and then solder the wires inside the car. otherwise your gonna have a bigger hole cut inthe rubber grommet and its not gonna be air/water tight
