This may be common knowledge for some, but I don't remember anyone mentioning this before. Anyway, when I was running the hoses (water and Freon) through the inner fender well (as directed), I found that the screws around the outside perimeter securing the fender to the inner fender well were very sharp (see photo) and intruded into the passage way about 1/4". This creates an opportunity for hoses to be punctured over time. Routing these hoses was not fun and I don't want to be doing it anytime soon, so I ground down the screws and carefully de-burred the edges. There are at least three, maybe four screws that can reach the hoses.
