There are a couple other way if you want more strength, you can use a boat front cover with legs that you can cut down to whatever length you need, Nicson, Glenwood etc. There are also some timing covers with the whole lower end being a flat plate, again some boat stuff by H & M, and if you really want strong, there is a cast iron truck cover with the flat plate, you just have to get the right one with the FE-size seal- 330MD IIRC
