I got a grand steering wheel for the mustang (the one that looks like it's really made for the mustang and has the little center cap and everything). So my question is for those of you that have these...how do you get the horn button on...the instructions say that theres supposed to be little notches in cardboard part of the adapter (where the 2 little disks touch each other to sound the horn) but mine does not have these notches therefore there is no way that horn button can be put on. What should I do to make it work? WE called the place we ordered it from and they said they wouldnt be suprised if the new one that they're sending us is the same way and they were absolutley no help to us...so what do i do to fix this?
