Hello, I have a 26.5 and I want to replace the mast base on the cabin top. The one I currently have is cast aluminum with toggles (?) which allow turning blocks to be attached to redirect the lines coming out of the mast. I don't trust the cast piece for one, and it only has attachment points on port and starboard. I want to replace this cast aluminum piece with a stainless steel assembly that has attachment points all the way around. I have seen these on other boats and I was wondering where they came from. Does anyone have any insight into where these can be purchased? Also, if anyone has done this conversion, any tips or things to watch out for? Thanks in advance, Clayton
