Wire wheel through 1935 were designed to seat up on two different levels besides fitting the drum diameter. The inner area around the hub snout has to protrude a fair amount more than the outer diameter outside of the lug studs. Special rings are generally used to adapt them to a later drum. I don't know which drums the OP chose to use but not all drums work well with the model A design wheels. The 39 Lincoln reproduction brake set up will work as will the old Ford 12-inch drums due to the taper of the outer drum shell. The later F100 stuff can be made to work but they are 11 inch drums and they are relatively flat. Most folks use a later type wheel so they don't always have to worry about wheel to drum fit.
These adapters work with flat face drums but they aren't cheap.
