what i did for my C which would probably work for the SRT8 was buy the E&G mesh inserts they happened to be the ones for the front. i had my front fascia off and just used the mesh. what i did was fit it on the lower ducts and trimmed off the excess mesh. then i bent over the corners and used epoxy to hold them in place. it worked great. i dont know if this will work for you. it does invlove removing the front fascia. here is what mine look like. hope this helps
