[quote=SRT SIX]No problems with fitment. Installation is quite easy using the existing mounting points. I will get exact warranty info and post.]

I have one of your lower units but have had little time to install it. I took a look today at the directions and I see it affixes to the original plastic mesh grill. Can you elaborate please on how that original is removed? I stuck a long flat blade screwdriver into the hole at the outer end of one unit and I dont seem to be able to find whatever device is present there that I have to unattach. Do you have any sketches, details, suggestions on removing the factory mesh grill units? Any help would be appreciated. Thanks...
