For your 1969 travel trailer, we unfortunately don't have a direct fit for your spindles. Your # LM48548 bearing is an agricultural bearing size that is not consistent with the electric brake compatible hubs on modern electric brakes. I've looked at swapping races and bearings and cannot find any compatibility.

My recommendation is to change your axle to Timbren Axle-Less Trailer Suspension System w Electric Brake Hubs - Straight Spindle - 3,500 lbs # A35RS545E. This kit will replace your current axles and give you new suspension, electric brakes, and the bolt pattern you desire. You simply bolt these assemblies to your frame in the axle location and add a 2 inch square bar (not included to the integrated assemblies. I've attached some videos to help further.
