I'd do frame off again no worries
Just do it. Order new mounts and hardware (ccot) and motor mounts(ccot) use ASE for the tranny bolts $8 not $100. I didn't do new wire harness. The trick to the body mounts is chop them with a sawzall if the bolts are too rusted. Have a fire exstinguisher handy if you are going to use a torch.
