The mast step on my B28 is stainless steel. I do not have a pictures but it about 1" wider than the mast on each side and about 2" Longer front and back. It has 4 raised places on the inside were the mast would sit to hold it in the center of the plate. it has 4 holes one in each corners so you can Lag bolt it down to the Keel. Had to trim mast 1/4 to remove some corrosion after 30 years. We then but 1/4 aluminum plate under the step separated with a be a piece of plastic. If I make to the boat this weekend I will see if it can get a picture.
