Same year as mine, maybe a different spec by original owner or someone has changed them out along the way. I have looked at Rig Rite's site and identified the spreader as a SP3 and the mast attachment plate I believe is on my boat as a K-11295. Now I just need to figure out The specs and characteristics of what I have. It seems that the spreaders are doing what they should and everything else looks good. I will do a little further research for sure and if I come up with something I'll post it. According to Rig Rite they should be attached via a 1/4" pin so I'll need to get one and replace the 1/4" bolt currently on the starboard side.
