Here is a pic of the EGR blockoff plate from an earlier question. It is fairly simple to make one as long as you use a piece of metal that is flat and smooth, and is thick enough to not warp. This one has been on there for more than a year with no issues. The original EGR bolts are too long, so I spaced them out with washers temporarily. My temporary became permanent as I forgot all about it. lol.
