just picked up a harbor fright trailer but it doesn't have the optional tie down brackets that extends out from the front sides of the trailer/frame. does anyone know ideally how far apart the two hold down points should be for the front? This is to load two bikes. as it sits, one eye bolt that is being used as hold down point extends right out of the front side of frame about couple of inches, and does not give the tie down much of an angle. would this be an issue?
