I was asked about the numbers in yellow on the hub. I can't make out the first letter or number on each hub but the next 3 on one hub are 56G? and the second hub it is clearly 57G2 anyone know if these are part numbers. These came of a June built car so they can't be week built numbers? Is it possible the first number would be a 1 for the 156 & 157 day of 68?
