NC3800,
Yeah, I misread your post and thought it was the passenger side that was obstructed. Glad you found the problem. Still, the original sized round mirrors are kind of on the small size. Some of the vendors sell rectangular mirrors which give you a larger field of view and they attach to bases like the originals. You can see what they look like if you click on the link to my COE highlighted at the bottom of my signature lines.
