    You do not want the diff from the 72 FJ40. It has a coarse spline pinion and you'll encounter flange differences. Don't know what, if any, stumbling blocks you'd encounter with the FJ80 diffs.

    Use the later one. The 72 is a coarse spline pinion and significantly weaker.

    92 80 rear is a FF application, you might get a headache with the spiders if you are just swapping in the third..

    I'd look for ones from a 62

    I did this on mine...got thirds from a 62. Actually, I got two "front" thirds IIRC. less wear and tear.

    No it isn't. The FF started in 93. The 91 and 92s and some 93-94 have semi-floats.
