I have a 88 pirata 23ft and just recently got a new tower that was off a brand new ski centurion I believe but the mounting hardware did not come with it. Where it connects to the boat it has aluminum balls about an inch in diameter. I was hoping to find the original hardware that goes with this tower but if i cant I will have some made. Wondering if anyone has used towers with these mounts and also if there is anything I need to know before tackling this project. Any advice is appriciated. Also I have tidal audios speaker set up with 8 6x9s and three lights in a custom fiberglass box that i might be getting rid of depending of the head room with my tower. If interested pm me it comes with a brand new wiring harness looking for 500 dollars obo ill have pics up soon of the tower and my boat.
