Agree with all of the statements about drilling out the rivets and replacing with rivets.
I actually did a write up somewhere about drilling out rivets, but in general, pick a bit just a little bit larger than the center hole of the rivet. All you want to do is drill out the wall of the rivet itself. You don't want to make a larger hole in your sheet metal or do any other damage.
Play with the pressure you use while drilling, typically I find more speed is better than slow speed. The rivet head may stick on your drill bit. Use a pair of pliers to remove, it may be pretty hot after drilling out.
If you use too much pressure, when the drill punches through, you might hit something behind the rivet and damage something. Something like the insulation on the power cord...
If you do find the sheet metal is damaged from you or a prior encounter, sometimes you can cover up mistakes with a washer the proper size for the rivet. In this case. that may mean you need to get to the back of the sheet metal, if you can access that area.
Of course, if you can access that area, or get your fingers behind the cover, then you might be able to use small screws with washers. I would be careful to not use long screws that might chafe the insulation on the shore power cord. Probably, the cord could never come in contact with the cord, but I know my luck.
