moving blankets, it's all about moving blankets.. but you'll have to reprime the front foot of the qrter and the b-post..
I may learn about back masking aft all...

moving blankets, it's all about moving blankets.. but you'll have to reprime the front foot of the qrter and the b-post..

is the tailpain sitting on the frame?
usually you can see em if you get a bit of it pryed up...
you should loosen all the bolts too... at that point you just have the fillet weld at the c post..
I'd get everything you can loose, loose... even the tailpan to qrter bolts, not unbolted but loose....
how did all the bolting up go originally?
and where is the rear cab mount on that rig again?

so the tailpan has been pulled down to the frame on that side?
that gap looks pretty decent... I'd burn it in in a few spots than unbolt the back and see what it does.. it may, or may not freak/buckle the qrter as the back comes back up.. it'll probably go 1/2 way back up on it's own once unbolted.. you may have to jack the tailpan a bit to get the last amount, and that is when you'll have to watch for buckling......
the last step will be doing all the qrter bolts once the welding and body mounts are sorted out..
