make sure to use the proper torque on the pulley bolts when reinstalling, I have seen/had pulleys on numerous vehicles shear the bolts, not due to any harsher driving conditions, but because the bolts had been overtightened which stretchs and greatly weakens the bolts, and it takes very minor stress to get them to fail.
The replacement crank timing cog that lowrange shows in their repair kit does have a locating pin.
