Fixed own problem
After writing my previous message, the dim light in my head turned on.
The previous owner must have monkeyed with the GDO and put the housing on backwards. Once I removed the entire housing, the Left Side of the GDO had the limit adjustment screws I was looking for. My previous thought process was that my model was slightly different than what the manual was talking about, since the manual includes 6 different models.
Anyways, as usual the problem was human error and not machine. I still am not sure why after 8+ years the door decided to alter its limit setting?
