It looks like that truck has an additional lift with springs , judging by the slight extra height of the truck compared to a factory "highboy" and both the front and rear driveshafts are in backwards, the sliding yoke should be at the transfer case end, and they did not have those double cardan joints. The rear blocks are factory
Nice video! I've owned three highboys back in the day. All were open knuckle disc brake trucks, 1976. Earlier models often had closed knuckles and drum brakes. Almost all 1970's 4x4's had divorced transfer cases, and the highboy had the strongest, the NP 205, a fully gear driven, not chain driven case. It really was a medium duty t-case. The highboy set the standard back in the day for snow plow trucks and landscaper use. The high ride height gave a better approach angle for off-roading, and the height made the use of large tires possible. The first readily available 35" mud tires, the Gumbo Monster Mudders by Dick Cepek, were designed with the highboy in mind. The highboy's axles were among the strongest pickup axles on the market. The highboy differed in having the front pumpkin offset to the driver's side, making it easier for the driver to judge it's position when off roading, and to avoid harming it on rocks or other obstacles. For it's time, the highboy was overbuilt. When the 4x4 exhibition truck craze began, the highboy was used as the base for the Bigfoot monster truck. Lifted pickups, large tires, you name it, it all started right here.
The reason they used the divorced transfer case is so that they could get the ride hight with the low pinion front axle and the combination of the long front shaft and the short rear one made an even torque distribution to both axles

Very cool thanks for that info. I am sure it will be in the shop again and I will shoot some more video. Tha ks for watching
That is an NP203 case. You can tell by the big two-speed gearbox on the front of the case, and the aluminum tail housing.
That's a good catch. I thought they were all 205 tc in the highboy. I learned something today. Thanks
Hi, my brother inlaws dad had one of those... his daughter took it off roading and rolled it. That was the last i saw of it.😢
Oh thats sucks
