Need to know what kind of hubs I can use?

If they’re factory drums it’s 5x4”. The disk/drum cars went 5x4.5” in ‘73 but the drum/drum cars stayed 5x4” all the way til the end of front drums.

What the heck happened to those hubs?! You know the drums are swaged onto the hubs right? As in, to get the drums off you need to remove the outer wheel bearings.
ehhh.....there were large bolt pattern 4 wheel drum cars, were there not?
I unfortunately did not know that the housing and hub where a unit. I had thought that the rust was the problem and used a harmonic puller to get the drum housing off. Never done this before and learning the hard way you could say.... As for measurments, it is 10 inches from outside of one shoe to the other outside of the other shoe.
