I imagine he used a hammer and chisel - to break spot welds. Then did a clean up and re-paint.

but the problem is the above cage is attached to the front which acts as a lock

Anything can be cut out.

any other suggestion from anybody else?

If its rivetted then a 3-4mm drillbit will get rid of them
