Boys
Riddle me this . . . what do the stamped numbers on the two batches of 750 rocker arms I've got signify (K2 and F1/2)?
I get what the 'A' and 'B' stamps are for, but each arm also has a two digit number on it - and there doesn't appear to be any rhyme or reason as to what they signify. Should I be looking to put matching numbers on the same sides, or are they just arbitrary batch numbers put on by the factory?
Thanks
