Hopefully someone over here has done this. I tore the rear out of my 87 4-runner(I'll post in the readers rides when I get a chance to load the pics) in the hopes of welding or spooling it. Its a barely street legal trail rig. I locked my 66 40 and thought this would be a walk in the park. Jokes on me. So the questions are: Why does an 87 diff seem to have an ABS sensor on the top? How do I get in there, Or has anyone done this(and have pics.) Or would the spool come with good directions. I have been in the search here and a bunch of other sites and none of those rears look like mine.
