Yes the sherman combo works well in the NAA. Have one in my NAA puller.You will want the one that has the course input shaft. The fine input shaft is for a later model. The step up and step down will also work but will need work because of the position of the handle and the starter bump out. It's not impossible but it's better if you can find a combo.
