Part # shown on photos along with measurements

Hello! This operator looks like an older version of our 39-172. I think this may be what you want, but look it over and see what you think. Take note of the orientation of the link arm and its offset. I can't quite make out your orientation from these photos, so that's an important detail to consider before you buy anything.
