I have one of those units already; kind of big and ugly. The currant box is mounted on the outside of the frame. I will be using a column out of a 1984 1/2 ton. I kind of like the idea of mounting a rack on the outside of the frame to pull and push the drag link. I had thought of that already. I want simple and dependable. I will try to post some pix later. Thanks for the input!!!
