I have a 1988 centurion falcon that I recently bought with a buddy for 6,000 and the thing is pristine. Can’t believe I got it still. But anyways..... the plastic mounts that hold the aluminum brackets attached to the swim deck broke. Like the mounts that are held in by 4 flat head stainless bolts through the hull. Where can I find new ones or should I just do my plan of welding a 1/2” aluminum plate to the swim deck mounts with bolt holes and get rid of the factory plastic ones? Sadly don’t have a picture right now so hopefully someone gets me. Thanks!
