8 3/4 green bearing a body axles fit

These were not the snap ring type . They had the plates on the bearings so you can not put them on wrong . The center pumpkin was not in when i installed the axle the last time also the pin was removed . I have reinstalled the first set of axle with oe bearings . The only other thing i can think of is that my other set i got are from a early a body and there was some kind of a space difference ?
