I don't see anything unusual. The splines on both the box and the arm look fine to me. I torqued it to the 1969 factory spec of 120 ft. lbs. because I'm using the original 69 steering box. But, being it is a 73-up style arm, I wonder if I should use the 73 spec. which I think is 170 lbs.? Just don't want to cause any damage to the steering box.
