We finally took my father's 4runner on an official 'wheeling trip today. He has spent years restoring it and finally it was nice to reap the rewards! I can only claim the suspension and stereo work.
Rebuilt 22re with torque cam, R150f (yeah not quite the 151 but he did have to get the bell housing from one), Toyota 4.88 3rds, rear loc-right, add-a-leaf with longer shackles, bj spacers, polyurethane control arm bushings, soft-topper, bushwacker flares, fzj80 wheels with 305/70 (33x12.5) goodyears, and a whole bunch of little extra things.

Even with the very minor upgrades it's really only limited to smaller obstcales, anything harder and we'd have to hurt the body to really use a solid axle.
