My '70 GMC has a differnent carrier. The bearing is just a standard bearing like you could get at any bearing supply house. there is a rubber doughnut that goes over the bearing. There are 2 large clam shells the encase the bearing/doughnut. This thing is stout. I should get some pictures of it as I have never seen another one, but surely there are out there.

Those are pretty uncommon, may have been a 3/4+ ton thing or a leaf spring truck thing. I know I've only seen a half dozen or so in the last 5 years.
A lot of prople think the car style or teardrop style carrier bearings are weak. Carrier bearings don't just fail, our 2 piece driveshafts can very easily be reassembled incorrectly, changing the timing of the bolt on yoke or putting the rear shaft in 180* out or even backwards will cause a vibration. Many people just think old trucks are supposed to have some vibrations and are completely unaware of why ther carrier bearing fails 3 times a year, some even go out and buy one of those fancy billet/poly supports instead of fixing the real problem, an out of phase and or ballance issue.
