I've got an 84 FJ60, and I've been contemplating going to 35" tires on it (currently 33/31, depending on season). Am I right that the 4.11 gears from a 40 will go in? What year did they change from coarse to fine spline? Also, will the powertrax locker i have go in the new diff? I'm thinking the whole third member swap would be easiest - would that work?
TIA,
Travis
