Spanky,I doubt if that one has a live tandem set-up. Not until after '56?? The rear axle was designed to engage,only on wet/icy/muddy conditions,could not be engaged unless parked,and 35 M.P.H. was top speed with both axles inter-locked. I took a video of a similar tandem G.M.C. Look at that for a reference. http://s1181.photobucket.com/user/willybickey/media/7-3-2013/MOV00219.mp4.html?sort=3&o=1
