I agree, post some more pictures; specifically of your brake MC so we can see how it mounted. As noted on here, the rod should be pretty straight from the pedal to the back of the MC (does have a slight angle perhaps). If the MC is in the right position and the rod is going from the pedal up or down at an distinct angle, you perhaps have the wrong brake pedal in the car (I think B body brake pedals are longer). As for the bolt, someone post the correct bolt early on, you need to have this because it fills the brake pedal rod end completely and gives a bearing surface, the threaded part goes through the pedal; think of it this way, the threaded part holds the rod to the pedal, but all of the rotation occurs on the fat part of the bolt (it should not be turning in the pedal), the O ring is there to keep lubricant in the pedal rod end where it is needed.
