I'm excited! I will do the measurements and let you know.

Hi Tom, I have some results.
The existing unit looks similar to the one in your photo but there are differences. First there is the photo named short arm.jpeg. This seems considerably shorter than the one in your photo. The photo named long arm is the bottom view of the longer arm shown in your dimensioned photo. This picture is included because it has a part number stamped on it. Hope that helps.
The other difference I see is that the pivot point of the long arm is pretty much right behind the centerline of the worm gear and not offset as in your diagram. See photo long arm pivot and worm.jpeg
The length of the long arm to it's pivot point is about 9". see photo long arm length.jpeg
Let me know what else you need. We'll get there.
Steve
