S280 corner removal

[Bryteayes]

I’m trying to remove a couple of the corner brackets on an S280 to put on the habitat extension of CARA (1998 M1079). They will be purely cosmetic but I think they will visually help tie the extension to the rest of the habitat. I have all bolts removed but the corner brackets appear to be held on by an adhesive. Any idea how to get them off?
Thanks

Are you sure that doesn't have structural value?

It has structural value on the S280 but will not on habitat extension.
