Anyone recognize this axle ?

[CH3NO2]

I have this axle under a homemade motorcycle trailer, the guy I bought it from thinks it may have come from Chrysler product, maybe Dodge/Plymouth but isn't sure. I need to know what it came from so I can get new spindles when the time comes. ( I have one spare now )
Ths distance between the plates that the spindes bolt to is 54" and the wheels are a 5 bolt 4 1/2" pattern. the wheel studs are a 12x1.5 thread and are not left hand on either side.
I have taken the spare spinde to an auto parts store but without a part number they are lost. I have considered taking the trailer to some local salvage yards to see if anyone recognizes what the axle is from but I thought I would try you guys first.

Thanks







Here is a picture of the wheels if it is any help, I think these were the original wheels, anyways the hub fits real nice..
