At the end of this season, when I took my mast down for winter storage, I noticed that the forward rivits that hold the spreader brackes to the mast have started to pull out. In addition, I noticed a small hairline vertical crack in the aluminum mast just above where the forward rivit is pulling out on the starboard side of the mast. I understand there is an approved after market replacement bracket that is designed to solve this problem. I am looking for advice on this from anyone who has experience or who may have some suggestions. Where can I buy one of these brackets? How much do they cost? If more than one style is available, which one is the best? What is the best way to remove the old rivits? Any help would be greatly appreciated. Thanks Larry Woods
