79-85 solid axles used a push/pull type of steering system, so they are incompatible with the IFS boxes. Basically all boxes from 86-95 are all the same strength wise. There were a few differences in the box from 86/87 and 88/95.

This was taken directly from http://128.83.80.200/taco/box.html

"The casting for the 86-87 box is smoother looking overall with fewer bumps and lumps and it has a lock ring around the steering input shaft. The bolt-on casting that supports the input shaft also protrudes about an inch less than the one on the later box but in all other aspects they are functionally identical. The input shaft and sector shaft have identical dimensions and spline counts so both boxes can use the same pitman arm and, if there is enough slip to accommodate the different lengths, steering shafts. The mounting flanges are also identical so either box will bolt-up in place of the other."
