What to Do?

I picked up an '87 Dana 44 today with the LSD. It's in great shape and complete from drum to drum. It's going under my '99. I searched about dana 44 installs and didn't see what I was looking for. I'm just wondering if those of you who have done this swap know of anything I should look out for or will it just bolt in? I read somewhere that the 44's yoke reaches out farther than the 8.25. True? If so, what can I do short of buying a custom shaft. I do not have an sye if that matters. Looks like the brake lines will be straightforward. All advice welcome!!

advice? build it up before you install it. installing a 21 year old lsd is not something i would do.

The D44 will bolt in. Install fresh seals at the minimum. The drives shaft may need to be lengthened. You don't need a custom shaft, any drive line shop can shorten or lengthen a shaft in just one day.

Measured from the center of each u-joint on the tube part of the drive shaft for 4.0L with AW4 and NP231.
