Detroit Timken made a 2 speed axle, but I'm not sure if they ever made a 2 speed tandem. Here is a diagram of Eaton vs. Timken tandem units. The Timken which later bacame Rockwell and now is Meritor used a through shaft. The 1950's Eaton had the interaxle driveshaft above the forward axle. This design didn't last very long. In about 1960 Eaton went the through shaft design that is the standard of the industry today.

As for the tires, the wheel I see on the drive shaft is a lock ring style that is relatively safe. It is still produced today. On the drive axle, the lock ring are on the inside and couldn't go anywhere even if a lock ring were to blow off. You have to be more careful with the steer tires. The lock ring is to the outside. If it is not properly seated, it can be dangerous. I run all tubeless tires on my fleet and have been for over 40 years. But I have been messing with tube tires for over 60 years. Here is a photo of my latest toy. I put just enough air in the steer tires that they stood up and then towed the thing 70 miles per hour in 100 degree weather. Unless the tires have been totally flat for years, bias tires are less likely to blow than radials. It was running them so slick that they wore down to the tube or running over a sharp rock that caused the old bias tires to blow.

Cren, I see the differences in the tandems....quite different actually. Somewhere I have some lit on the Detroit tandems, and will post pix if I locate it. Good luck getting it home, Smangy!

The Chevrolet Walking Beam/Power Divider setup was made for GM/Chevrolet by Truck Equipment Company starting in 1956. Prior to 1956 Chevrolet Tandems were dealer/owner installed from third party vendors. I'm not sure if GMC used the same set up or not...

On the bigger trucks Chev and GMC diverged quite a bit. It wasn't just GMC engines and different badges like on the medium duty trucks. Maybe I'm commenting on the obvious here but be careful about assuming what you find in the Chevrolet book applies to GMC. Then there is the confusion over what was produced for the Canadian market. I cannot speak to that as I have only worked on US GMCs and Chevs. The three-speed power divider is a new one on me and that alone might make the truck worth restoring or at least preserving.

You might also look up the ATHS (American Truck Historical Society). Their members mostly focus on heavy trucks, like what is now yours, and heavier. They have chapters all over the country and regional shows and a national show annually. I've been to seeral nationals and they had upwards of a thousand entries. The National in Yakima WA attracted lots of logging equipment from B.C. Jim Carter was there and I talked to him at length. Nice guy. They skipped this year but a couple of the regional shows went on.
