How did you get them to fit? the aluminum on the bracket is thicker than the black mounting piece. In other words how did you recess them. I am looking at drilling a hole large enough for the whole assembly, but not going all the way through, and then drilling the 7/16 hole. Is that basically what you did?
BTW they are pretty sweet. I have to get another set though because the Autozone only had 1 set even though the computer said they had 4 on the shelf. They are hard to find. Look in the LED section. Or the import section.
