Thanks for the feedback guys. I was trying to avoid the aluminum contact with the stainless screws but maybe I can slip some nylon washers in there. I guess Stainless backers are fine, too, if a little heavier... Your arch looks awesome John123. Your Tsunami is incredible. I'm working with a pre-owned arch that will offer functional utility and little more - but hey, it cost me a case of Stone Pale Ale...
