This is the opportunity of a lifetime. He said he'll swap your rear end with the John deere unique rear end. He said it'll take a little fabrication but can be done. He recommended it and says it's a must. He has to make a new drive shaft which is made from a stick and assured me if it broke it will be replaced by one in his yard. This will run you a couple gs easy but once your done your truck will be a bad mother!!
im pretty sure a john deere axle will fit in the front too. just swap the gears for some 8.52's and you'll get great gas mileage. replace the oil with some 250w 40 oil
