Hi Alex. Just to let you know, all I am doing with these toolboxes is covering my shop time and materials. It takes me 7 hrs to make one start to finish. They are made out of 1/8" steel and completely welded together with a drain hole in the bottom. The studs are welded on so all you have to do is slide them through the existing holes in you loader frame and install the washers and nuts and tighten them down. They have 4 coats of primer and 4 coats of Kubota orange paint. They weigh 14 lbs completed so very heavy duty. With shop time and materials they are $150.00 plus shipping. If this works for you, let me know. Thanks Ron.
