Robert. Trailer was designed to fit the hull as the weight of the boat when dry at 3000 pounds rests on the bunk boards. If not you create damage to hull particularly the seal of the water ballast tank. It will be hard to find the exact trailer used as most keep their trailers with th 26 or 260 as the trailer will fit the hulls both being the same hull.
Magic Tilt built the 260 trailer and has the design should you go the new route. If so make sure of state requirements for brakes on one or both axles. Suggest surge vs electric brakes
