I'd suggest that judicious use of a sharp, narrow (1/4"?) chisel with a small hammer could undo the peened square tube sufficiently to allow separation. Perhaps a spare piece of square bar in the peened hole would help to control the chisel's action. I have done this on (non-car) locks in the past with some success.
Depending on how much metal remains on the very worn-looking face I'd be tempted to braze or silver-solder a square (or even a stirrup shape) of steel sheet over it and file down to the original section. Take great care to avoid overheating that paper-thin part.
