i have the DXF file for the mtd torque converter cover's mounting bracket on my site. Used autocad to draw them up. that's probably where most people got the file. you can always tell my version because there are small 'v' cutouts on the side, where you bend the bracket (that was not part of the original mtd version, but added them to aid in the bending of the bracket.)
