Are you referring to the pivot bar? On the S140-11 store page, you can see two pivot bars shown under "Related Item(s)" on the right side of the page. These are our 26-398 and 26-405. One of these may be what you need, but you will have to carefully go over our measurements and pictures to confirm the better match.
