The 79-128 was used on the older style doors made by Arch Aluminum. These pivots have a flat face while our 79-126 has a rounded face, and was used on Amarlite commercial doors. Would that still work for you?

If you aren't sure, send us some photos of your door and pivot set. Also look at the door to see if there are any Labels on it that identify the manufacturer. Offset wise, you are only talking about 1/16" difference. My concern would be the mounting hole locations. Take a look at the related videos, as well. They may offer some insight.
