Got these installed. Of course I haven't tested them, nor have I welded them. None-the-less they are nice! A side effect is the rear end has been lifted 1". As a result I will lower my Jeep on all four corners to net a better center of gravity. Thanks Brian at HD Offroad Engineering.
Here I had to cut two slots in the subframe to access the nuts. For some reason the driver's side didn't have a nutstrip inside the subframe.
