I really wish I could help you because I did a r&r on my 4x4 95 Dakota but it sounds like your set up is defferent than mine. My front diff. is connected to my motor mounts, which the front diff. had to come out in order to remove the trans. Alot of those bolts that I removed were in ackward places and had to come in under the bumper with about two and a half foot long extension to get them, because there was now room to get to the bolts or nuts with just a wrech or socket wrech. The best advice that I can give you is look from the outside of where this bolt is at and see if you can come in through the fender well or like I had to from under the bumper with a long extension. I wish you luck it's a real pain but once you get it back together it will have been worth it.
