For what it's worth, you have my support in your ambition to do something good for us members who would like a set of these vents for the rear bumper to replace those reflectors. I think if you or someone on the forum could contact the maker of the JDM vents, we could find out if with some slight mod to their vent, they could come up with one to fit the USDM bumper. Just a thought. I'll look into it and pass on to you what, if anything I find out. Regards, Jim
