Body bolts

While I am waiting to pull the engine and transmission, I have started to loosen the body bolts.  Well, looks like all are easy except 2 front bolts.  One is locked and the other is spinning.  They are not designed to be taken off easily, especially if there is any rust.  The bolts go through the body and have nuts inside the frame holding them in.  These nuts were originally spot welded in place inside the frame before the frame was enclosed.  Now the spot welds have broken and the bolts are free.  There is no way to get inside the frame to get on the nut.  All restorers have stated these bolts must be cut off or the frame box unwelded to get to them.  Looks like I have some cutting ahead of me on these two.
