Wake towers are mostly a one size fits all as they have adjustable widths, and many have adjustable rear supports. I really like the towers that have lines that follow the side glass frame. If you need it to fold, make sure it folds low enough for your store space, and, doesn't put weight on your eisenglass.
I reinforced the mount points when I installed my tower using a couple of sheets of fiberglass and metal backing plate. Use a level. I was able to find a high point to hang the tower from while I got mount holes marked and drilled. Be careful when drilling gelcoat because it chips easily. I've heard that setting drill in reverse works well, but I covered the drill points with tape and used a sharp bit.
