Take a grinder and grind them down flush. Done.

I fonly that would solve the problem. I've got to install flanges, same
dimensions, over top the place where the original s stood.


It may solve some of the problem. Can you turn the flange 90 degrees and use
new holes? Or drill new holes in the flange at new locations?
