Hello, I agree that the 81-156 would be our best replacement option for the roller assembly shown in your photos. The dimensions look close to ours but the hole spacing is a bit off. With that being said, I would recommend double-checking your measurements to make sure that you are measuring between the center of your installation holes. The 81-156SS is the stainless steel version of the 82-256, meaning that it would hold up better in areas close to salt water and large amounts of moisture. If you decide to give one of these a try and run into any problems, our return policy can be found here. Thank you. Alternate image for 81-156
