Fix it . . . and do it the right way (which is body off). Once you can actually get to the thing, you may find that you need cutt-off wheels or carbide burrs . . . whatever it takes to cut the weld and move the rear cross. My guess in that the original rivet holes will still be there, so it will be obvious as to where it needs to go "back too". Taking the body off is a fairly sizable job (as the fine threaded bolts just tend to be rusted and the cage nuts may not hold) - but you'll get through it. If you damage a cage-nut, or they are just shot, you can buy new ones and spot-weld them back in (that is what I'd do - as you have the body off!).

I'm sure you'll be very happy that you put the ole' girl back in the right form!
