Hi Ron; we don't have a way of knowing which leaf springs are on your 2023 Montana Legacy 3123RL so you will have to identify them to find the right size. You need to find the capacity of your axle as well as the leaf spring length. If you don't already know your axle capacity it will be listed on the axle tag. For the length I recommend measuring the flat length to be the most accurate. I have attached an article below which explains how to measure.

For example, if you have a 7,000 lb axle and your measurement was 26-3/8" you can use the # e64SR you were looking at as a spare. I went ahead and attached a link to all of our leaf springs below for your reference. You can also comment with your measurement and I can find a spare for you assuming we have one that matches.
