IML: 1957 Imperial Bumpers

[PiscesM21@xxxxxxx]

     I have a rusted out 57 Imperial, I have tried to take the bumpers off but they just won't unbolt. I have tried everything to get them off and apart with everything,   except a torch. Does anyone have ideas,   as I am disassembling as much of the car as I can.
     I have acquired a 1957 Chrysler Southampton, in the exact same color to replace it. It is missing the drive train, so I'll remove the drive train (392 Hemi& auto), and put it in the Southampton. 
     I appreciate any and all ideas so I can get the Southampton running.

Thanks,
