Infiniti G35x license frame

Just bought a 2006 G35x from a private party and got a new license plate for it. For the life of me, I could not remove the old license plate. The screws are loose but would not come out at all. Very difficult to see behind the plastic frame that hold the plate. Does anyone know any tricks for me? Thanks.

Slide a hacksaw blade behind the plate and cut the rusted/frozen/stripped bolts…Tape up the end of the blade to make a handle…
