Wile we’re on the subject of COPO ring and pinion gears. This is a set of what I believe to be 4:56 COPO gears. I got these with an 0428 BE. My question is why the difference in the stampings and the location of the stamping on this set of COPO gears vs the set shown in the previous pictures. Was this a service replacement set. Eric, anybody, any idea.
