Yes, Just order them b/c that is a common wear part, so I am confident that is your problem
When you get them, just have somone on top shifting the lever a little back/forth while you are down there w/droplight..you will see the slop right of.........
The NSS has provisions for rotational adjustment, but with bad bushings, that is seldom needed b/c the new bushes put the levers back to original positions.
