I ended up bending the feet out slightly, closer to 90 degrees. They are pushing in the top roof ever so slightly but it springs back to normal when removed. I refused to trim the roof and I almost had custom feet made but after having tested it I was relieved to find out that I didn't have to.

How did you mount the rack to the gutters? Did you trim the edge of the tropical roof?
