so i want to go with taller gears for my 2wd toyota simply because it tops out too soon. i checked the vehicle code which was F292. that meas it has a 7.5" diff with 4.10 gears and it is 2 pinion open diff.so i was thinking of just getting an 8" from an 85 or older 4wd truck and then buying a new ring/pinion. who would be a good place to go through.
