OK I am getting a 700 R4 for free pretty soon, if nothing else it can sit for parts for some future thing or a friend. But I'm thinking maybe it should go in the K5. But the k5 has 39.5s and 4.10 gears. Would it be crazy to try and wheel with that setup? The K5 won't be on the street just off road. Someday I will get 5.13s in the axles but thats not in the budget at the moment(hopefully next summer).
