Help with a Ford Maverick

[68Coupe]

Looking for some ford experts to help out. We have a 72 maverick suppose to be a 5 lug car from the factory.
We bought new front drums for a 72 Maverick but the don't fit.
the center hole on the drum is just a little under 2.5"
the center of the hub that the hole has to fit over is just a little over 2.75"
did someone change these hubs a some point, if so anyone have any idea what the may have come off of.
there are 4 different sets of numbers on back of the hub, is there anyway to look them up and see what it is.
