I wouldn't recommend using one of those Rick. I have seen more than one blade bar break one half of the blade off on the side where the adjuster was mounted. The better way to do this is make a clevis style post that mounts off the center lockbolt, thus allowing both blades to move freely. You'll need to machine a shoulder onto the bottom of the clevis so when it tightens up the shoulder acts as a guide in the bar housing and still allows the blade to rotate fore/aft smoothly. Hopefully this makes sense. See attached pic-
