Great tools and great price! I used a smaller tool to install (16) 9/16" bolts on a 1997 Dodge 2500 and it worked great! I used a half inch breaker to pull back the cleats with this tool and everything went very smoothly. on stilettos is still perfect. It may have messed up the nut's threads a bit, but not enough to render it unusable. I had spare parts that could be used. I highly recommend using some kind of lube on the threads and spraying some on the bearing.
