If you remove a cover/case/s from your motor with varying length fasteners, all you have to do is drop all the bolts into the holes and compare to see that they all have the same gap form the bolt head to the case. If if end up with varying gaps just move the bolts around to obtain the same gaps and you will be good to go. All the case/cover bolts will generally have the same amount of used thread.
