Grant horn button help!

Yeah, the pieces you showed in the video, including the spring is for a stock column, I have 2 or 3 of them kicking around here. That's kinda why I was thinking you need the Ididit adapter. I'm assuming (and we all know what happens there) that the horn mechanism would be inside of the Ididit adapter.

It sounds like the Grant techs are stuck on stupid about the kit and mating it to the Ididit column.
