if there isn't a star type pattern on the bushings (seen from inside the magwell) then it's not staked in.
you will need to heat up the bushings a little to loosen up the loctite. also use the proper bushing driver and you shouldn't have a problem.
an alternate method is to remove the panels, use red loctite to install the old grip screws in, then remove the bushings using the grip screws.
