serious juju

Good morning guys, we just purchased a new to us 2007 270 CR, we love it but have a few questions I looked to call Monterey to but there site has no phone numbers for them, at least not that I could find ( not the best in my opinion) what I am looking for is the diameter of the front SS rails, I want to get some clip on fender holders. also is the an insert for sink on deck that gives you more counter space? any info would be appreciated
