Matt,
Mine is mounted on th edeck side, directly in the center in front of the live well. I have a 3/4" thick spacer between it and the glass as added support and the holder will then slid into the bracket in either direction, facing inward or aft. The magma Bait borad i purchased as a complete set and it included the adjustable rod holder bracket. I have srainless bolts with nylon nuts and washers on the inside. There is only about an inch or so between the interior of the live well and the outter wall. so it required me to use one of those special tools (spring loader grabber found in tool / auto stores) it only cost me four bucks and it comes in handy if you drop anything down in the bildge. I used it to hold the nuts while i was able to start the bolts, it required a second person becasue my arms arnt that long. Once they were started, I kept them from turning by usine an open end wrench which slid up in there and them tightened them from outside. I have used it a lot and it supports the weight of cutting on it wiht the bait board and will take any rod. works for me.
