its a long box and its on a 75 4x4 frame and the bed is just loose as hell, and starting to twist a little. im gonna have to take it off before i get the bolts because its a 59 long bed on a 75 1/2 ton 4x4 frame and ive got no way of knowing what bolts ill need, so ill just save them all and goto home depot, the problem i think is going to be finding the rubber spacers. does anyone know where i could get them?
