im buying a truck and selling the k5 and swapping my running gear from the k5 under the new truck. the new truck has 400/205 combo, and my running gear has 5.13s. ive got an overdrive tranny im going to swap in as well as a doubler im going to build. right now i have the money to do one or the other for now (tires or tranny/doubler). if i buy the tires, 5.13s w/o overdrive will be manageable, or i could build the tranny/doubler and then wait to get the tires. if i get the tires, the rig will be driveable immediately and i can take my time with the doubler, if i do the tranny/doubler it maybe down for some time, and then it still wont be as streetable til i get the tires. which ever doesnt get done, ill have the funds to do in May. which would you do first, and why?
