Go a different direction with it. Use a 23/64 drill bit to enlarge the hole and then thread the inside of the guide with a 7/16-14 tap. Screw a piece of threaded rod into the guide and set-up a bridge across the seat area. Use a well-lubed nut and flat washer to pull the threaded rod upwards. You will need to build the bridge high enough, -or use a piece of 2" pipe to raise the pulling nut high enough for guide clearance as it comes out.
