Yep, that makes a lot of sense. Something along the lines of this, right?
I had this in my bag with the fasteners for the front brake line. Unfortunately, I'm not quite sure where it connects. If I try to connect it to the rear fender bracket, it pulls the brake line too low (in fact, the brake line won't even stretch that far).
I know it went somewhere, just not sure where. I'll try to look through my old pictures to figure it out.
