No hardware mods required. I just cut three blocks of wood the height I want and rest them on the outer edges of the lower grate. The middle grate rests on the blocks. I have a collection of blocks of various heights, so can easily position the grate anywhere I like. The blocks do not burn but do get black and grungy with use. just make new ones when the gross factor gets too high. I think the ones I'm using are a year old, so its not a big deal. I have used this technique to create up to four levels in an 18 inch WSM including one level above the main grate.
