Not good pictures of my Bronco.
Engine is 4BTA, transmission is THM-475, Dan20 transfer, D44 up front and 9" locker in rear.
35" tires with 3:50 gears, allowing for 2.78-1 final ratio and max of about 77 MPH at 2500 govenor.
Gearing is right for the diesel. Overdrive - maybe one day. 23 + 12 fuel tanks - mileage 22-27 MPG.
