A solid 3" like OME 751 coils in the front, and 762's and D1 coil seats in the rear along with a set of extended OME Sport shocks.

Ditto, that is the set-up.

Things to remember with that tire size;
Performance is likened to that of a tractor as well as single digit gas mileage.
You will rub on the A-arm at full turn and any looseness in your suspension will be accentuated.

If this is a daily driver and you put a lot of miles on each day 265's maybe a better option.

Another consideration you should be aware of, 33" tires, besides cutting your mileage by 2 to 3 MPG, cutting your low end torque it will also tear up your spider gears in the diffs.
New locker with 3 spider gears are really recommended so you do not break down when off road.
