Well, the steering wheel can go on anyway although the horn wire wont line up. There is a little margin for error, like 2-3*, but not 180* . If the rag joint was 180 out, the lock ring would be 180 out, the t'sig cam would be 180 out and it would require more than 1/4 turn to get the signals to cancel, more like 1/2 a turn. Thats why I suggested seeing if/where the t'sigs cancel at.
