My old Mojo has cup holders at the rear corners. It wouldn't take much to machine an insert that would replace those with rod holders. Go ahead and make a couple hdpe rings for the underside to reinforce the glass and screw them down. If I can get the angle similar to Taco Marines video, just order the kit from them and done.
The front is a different story but the point of the boat is to have some sunlight....lol
