A spring like the # e69SR you looked at may work if you have a 2,000 lb axle but you will need to know your axle capacity to be sure. The diameter of a square axle can't be used to determine capacity so I would look for an axle tag or check with the trailer manufacturer. To account for flattening of the leaf spring I would measure the flat length which is outlined in the help article below. The # e69SR has a flat length of 26-1/2" which isn't far off from your 26-3/4".
