I have the Patric's gears in the Torque Tube on my '49 1/2 ton , tired 235 and tall (?32"?) radial 16" tires allows me to haul right along @ 65MPH all day , I was clocked at over 75 crossing Death Valley and it still hauls & tows cars just fine .

Do it , you'll like it .

There is no problem so difficult it cannot be overcome by generous application of brute force & ignorance
