And let me add; I welded my CJ D30, some time back.60/40-sorry I did. I could not understand the "U can't steer it" advice! It's great, as long as the tires can slip, & spin. BUT, when U hit hard ground ground, U have to unlock 1 hub, to steer it, & it's still hard to turn, with the hub unlocked! DON'T DO IT. Any kinda of locker, will be better!
