Hey guys, I need some advice. I'm planning on installing my snorkel today. I made the 60 mile round trip last night to go into town and get the appropriate drill bits and hole saw. Since it was after work, the only place still open was Home Despot. The snorkel install instructions call for a 92mm hole saw. The Despot only had 3 1/2"(89mm) or 4"(102mm). I figure that 92mm is pretty close to 3 5/8". What size did you guys use, that is, did you find a hole saw in a 92mm or did you use some other size? Any other last minute tips would be appreciated too. The sweat is already forming on my brow.
