That sounds like the same thing I did when I put my cam in and stuff. You'll have to remove/back out the little set screw/bolt that is in the side of the receiving part of the coupler before you re-stab it. It took my roommate and I like 6 hours to do mine, but that was after figuring out it had a set screw 5.5 hours into it... good times! The easiest way to do it is to set the wheels straight, un-bolt the coupler shaft from the steering box, stab the other end, tighten the set screw if you desire (left mine out), then raise the cradle up a bit, re-bolt the shaft to the box, then finish up.
