i have owned a few yjs back in the day and i just picked up a tj for a awsome price. comes with a 6inch lift that is still in box. im gonna either run 33s or 35s. i know dana 35 can handle 33's but im iffy on putting 35s under it. what should i do put a 8.8 under it or upgrade the axle shafts. if i upgrade shafts where should i go to buy them
