Fastest/easiest way I can think of is to make a T out of 2x4's .... drill a hole for the EZT pole to fit thru at the bottom of the T, allowing the board to lay flat on the bottom of the boat, and make the top of the T long enough to reach across the front of the boat ... then attach your rod holder bases to it. Might depend on whether you have a foot controlled TM or not, but even a upside down triangle shape with the 2x4's could be used to accommodate the foot pedal, if you do.
