Probably more common these days that some of us sailors get our boats from other sailors who have taken their boats apart. I have a 25 foot Lancer with all of the mast block parts in a box. I’m not sure how to configure the top of the mast blocks. Could I tempted someone to take a picture of this and post it? Anxious to get my boat on the water and this is a clear stumbling block. Thanks in advance. Greg
