I just recently picked up a Flight Control Tower off of a 99 air nautique for $300, in hopes that it would fit my 1990 Advance that I am restoring. Sooooo close. Unfortunately the base plates on the front of the tower are about 2 inches wider than the bow forward of the windscreen. The rear feet are perfect though. Any one with some TIG welding skills should have no problem fabbing up some new front base plates.
Luckily the guys down at Diamond Back Towers are going to work their magic and get this tower mounted for me. I will post up some pictures once I get it on.
