Okay... the lift! First try...
Far more stuff to unhook than I realized. Tail lights, gas fill spigot, backup sensors, license plate lights, a couple of vent hoses for who knows what...
The lift, second try... had to get a little more slack and crane reach so I removed the tailgate.
Here is the gap from above and below (blue sky) that I am trying to close...
Clamped the flange. Drilled some 1/8in holes and installed a series of steel blind rivets with my old Marson rivet gun to close up the gap. Did take me awhile to locate that in my shop!
Coached the bed back into place and the gap is pretty much gone!
Sure helps to have the right tools... along with my new HF 2T cherry picker w/ load leveler attachment, I used a pneumatic impact wrench with T-50 bit to remove the bed bolts (was nervous but they came out pretty easy) , cordless right angle drill for the tight space between the cab and bed, an impact driver, and a pop riveter.
All told... only a three hour job!
