Rally Wheel Question

[HatGuy]

My 72' Blazer has rally wheels on it.
I don't think they were optional untill
74'. Maybe the previous owner got them
from a 74'.
Here's the Question. One side has a
center cap with a 4x4 sticker on it
and the other side has the chevy bow
tie on the center cap. What is correct
Thanks

73 is the first year for those and they had the 4X4 emblems on them.
