Changing the "oh ****!" handles

[notorious]

The rear seats roof handles that you normally grab when car hits a bump are scratched by previous owner. I don't know what you have to do with them to get them scratched (sharp fingernails?), but this is reality.

I need to change those handles, but ELSA suggests it's not just a couple of screws, but it also welded to the chasis, so I'll need soldering iron experience for this kind of operation.

If anyone did change those handles please advice. Thanks!
