[Spridgets] Rear axle housing

[Frank Clarici]

How can I tell a wire wheel axle housing from a disc wheel housing if 
all the axles have been removed?
I want to get rid of some wire wheels because the stack is so high it 
falls over, I also have a 1/2 dozen or so wire wheel axle shafts i would 
like to get rid of and my $50 project car seems like a good place to get 
rid of these unwanted bits.
So I have a couple of axle housings (banjos) stacked up at the coop, how 
can I tell which is for the wire wheels?
The banjos are stripped bare.
