another pic of the LS6 brackets.
Both these brackets are made form the same die
If you turn them over the die left a machineing mark on both of the exactly the same.The stamps are different because the stamp punch was put in upside down when the die was sharpened and then reinstalled.You can also see the differerent dept of the stamps.Thats because when the die was sharpened the number punch was ground so that it sat in the die higher than its origional setting by about therefore
striking the bracket a little lighter.
