Strong, I guess so, they are stronger than a D35, the are probably of equal strenth as a D44, 30 spline axles??. The good part about toyota rears is that most of the "sr5 tacoma" rear ends are a high pinion rear end, but are hard to find... as for width, depends what it is going into? A cj, it is a similar width from the Wheel mounting points, as for YJs and TJs, they are about 2.25-2.75 inches narrower (depends on year and model) A better choice would ne a 8.8 out of a 95+ explorer, easier to find, 31 spline axles and disc brakes!
