Very cool! Notice the steering... that's one thing I couldn't get used to on the T I had. Wheels will over-center and just about rip the wheel out of your hand.
The first 4-wheel option to come on the market for Fords, was in the mid-1930's, with the Marmon-Harrington, fitted to the V-8 Ford, mostly trucks.
GAZ parts may be plentiful there, but not so much here in the states. I would love to find one of those front axles! Are they 3.78 ratio like the Model A's? I am also of the thought that a lighter Model A would not need two sets of springs on each side. That seems like overkill and must give a pretty rough ride.
