yes the 8.8 from a ranger will bolt right in. it will be slightly wider, but not enough to really notice anything. the only thing that may be different is the flange for the driveshaft, depending on what your 87 has, it probly has the smaller one, it was around 89ish that they went to a larger flange for the rear of the driveshaft. this can be easily solved in a few differnt ways, you can either get a conversion u-joint and use your driveshaft with the conversion joint in the rear and the flange from the larger size driveshaft. or you can unbolt the flange from the pinion on your 7.5 and bolt it onto the pinion of the 8.8. or you can get a newer D-shaft and bolt it in... all 3 of which are pretty easy and the newer driveshafts (90ish-up) use slightly larger u-joints.
just looked at things, with your ex. cab you probly have a 2 piece rear driveshaft with the carrier bearing, if so it would be a wonderful thing to swap to the 1 piece shaft from a 98-up 4x4 ext. cab ranger (unless you need custom shafts due to the v8 and different tranny and t-case being longer or shorter...)
