So, tried the 5/8's wrench route. That didn't work very well. Not willing to spend the $70 for the Melling one. So, gonna try to make one myself. Figuring I'll take two plates of 1/4" steel and weld em together. Run a 1/2" bolt through em and stick it all together. Cut it in half, and run a couple bolts to clamp the sides together. Should be all good to go. If anyone else has made their own tool, would love to see what you came up with.
