How many body mounting holes are there besides the two front ones near the door hinge pillars? Which two body holes were a half a hole off?
I haven't worked on a panel before, but if the clear majority of the holes line up, I would say that majority rules and you can simply drill the misaligned holes in the body oversize to get the bolts through the frame.
