Since the failure point on these is typically the main plate breaking off the mounting “strip”, I would suggest to not discard the pieces. It would be possible to fabricate some sort of fix. There was a post where one member heated up some fine stainless screen/mesh and melted it into both pieces to reinforce them. Alternatively a new attaching piece could be fabricated, possibly 3D printed, that the main plate could then be secured to from the outside. There are options, just have to be creative. If you have no side plate at all then obviously this isn’t going to help.
