Married box

[truckabilly]

I have a dumb question for you guys. If there is a married box in a COE truck, is it shifted by one stick or two? I can´t see a spot where the linkage to the AUX would enter.

Some but not all were electronically controlled by a small  switch on the side of the shift knob. When I first started driving for Union Oil Company in the late '60's I drove a '59 GMC Flatbed with several Oil and Kerosene tanks that could be pumped off at commercial sites. The bed would also hold 8 - 55 gal. drums and had a power lift gate at the rear.  In that particular application this  functioned as an under and over drive.
