Well I have had the rear lowering hangers for a few months now, so I figured I would get up this morning and install the hangers. All I have to say is, it is not an easy mod!! But if you have a torch and a good friend to help you take the bed off the truck, it will save you hours of work.
before I started

took the bed off

torched the heads off the rivets.

and bolted the new hanger on with the supplied bolts.

I did it all in 4 hours and never even dropped the gas tank.

After is was all done it looks good, but I need to do a c-notch and get some movement back in the rear suspension.
