It may be worth looking at Titan's Series I tower. It's a little bit higher than what you're looking to spend, but for that extra $95 you get a tower that is custom made for your boat, and features all of the unique aspects that make Titan so great.
On slightly older boats that have been outside in the sun, the resin used during construction will be more brittle due to UV bombardment. Because of that it is especially important that the tower on the boat be designed to minimize sheer and load forces applied to the deck. Titan uses a proprietary triangulated design for a very stiff tower, along with heim joints located at each mount to isolate the tower from the deck of the boat.
