Transmission Mount Removal

Boys, this thing has got me fuming. I took a look at the replacement mount. There are 2 steel "L" type plates that go around the outside of the rubber. It is one of these plates that is under the bent tab I was talking about. And it ain't coming out. My only thought is to grab a cut off wheel and remove the tab. That should allow the rubber mount to freely come out. I would hate to go against the factory design. I'm sure it's there for a reason. Anybody have any ideas? Thanks again.
