61/62 balancer pulley bolt id

[Joe M.]

5th ed judging guide makes no mention of the headstamp on the pulley to balancer bolts. I have two different bolts, one with an 'E' and others with 'wbr'. Which is correct for a 61 and which correct for a 62? Working on both engines

Joe,
Through out the 60's the RBW marking is most prevalent in that application. But I would not rule out the E. Both are viable suppliers for GM. The E (in my exposure) is more common in the earlier 60's.
