I made a spacer to use the Larin lift. I started with a 2 X 8" and nailed narrow 1/4" strip on top that fits between the frame members. I had to cut out on the left side to accomodate the jiffy stand mount. When I use it, I find the use of a bungi cord to hold it in place until I get the jack up to it works great. One can use a small eye screw on each side to hook the cord. Perhaps I can get a picture soon to show you.
