Glad I could help. What is the difference that you were looking for from the others? What is the '73 only' part? Just so we all know / understand.

Sure i will, just didn't think about it, if you look at the -73 you will see that the arm that the dog bone that runs paralell to the fire wall is on the lower part of the riser, that makes the dog bone sit in a angle of 10 -15 degrees, now on the photo esprist posted, the arm in on the upper part of the riser witch will have the dog bone in a horisontal position, hope this make sense.

It became apparent when I realized I had the 69 just 8 feet from the 73 and compared both of them. :stupid:

It is the pivoting lever itself that is different. Learn something new every day.
