My story is: I had purchased a good condition Linn Ekos MKII online from a seller but the seller forgot to put in the 3 bolts and teeth washer for locking the collar to armboard, so I cannot instal the arm. He sent to me a week later on the 3 bolts and teeth washers which the bolts head mark with " FKE 12.9 ". I feel a bit embarrass to ask the seller. The Ittok LVII I have with the 3 bolts for collar but no marking on top. So... are the bolts with "FKE 12.9" the original bolts for the Linn Ekos Collar?
