ok so i got a #5 crank pulley from Herb101 to put on my 04 lightning and im not sure if its going to work. my mechanic looked at it the other day and saw that theres one big allan bolt holding the stock one on where as the #5 has 3 allan bolts. do i have to take the other pulley behind the crank off to bolt the new one on. has anyone had their pulley put on and run into this.i really hope it will work.any input iwll be appreciated.thanks
