Having a hard time getting a good clear pic of the transfer cases used. Axle pics are easy enough to find, but nor the 'cases. Here's one that I did find http://media-cache-ec0.pinimg.com/originals/6e/c6/af/6ec6af1caf1cfc2d572b23ddf6bd9ed6.jpg. It's in a '52 Chevrolet, claiming to be a "3800", but everything about it screams 4100.
