Most intriguing. Do you have to cut them down? Have also heard of people using #6x 3/8" type AB sheet metal screws which you should be able to find even cheaper. There are a few other related products like the Stabilicer replacement cleats which are purpose built, but I've never used them myself. I do know the first SIMMS set of cleats was the last one I was going to buy...but they just haven't worn out yet...
