Correctly sized philips was all it took. Came off right away. So all set to put it back together tonight.
Any tips on removing the screw from the white plastic bracket that needs to connect to the new part? It is not loosening on the old one at all. New mini-philips on order to see if they will fit better and hold but I don't think this is going to come free. Does anyone know where a new white plastic bracket can be ordered?
