Well I ended up getting it trough spmotorsports, for a little a less than $100 w/crank bolt, shipped. Performance Ford never replied to me. My mechanic spent a large amount of time researching this vibration before he started throwing parts at it. After reading several TBS he found out that the damper could be the problem. I don't personally know if this is true but it makes sense to me. The key could of sheared is the only thing I can picture. I will know in one week if this is the problem.
