Hi everyone. I'm in the process of removing the ww motor from my '62. Its a 2 speed motor with washer. I have the windshield wipers and the louvered upper cowling off. I can't seem to figure out how it is attached to the firewall. I have a repair and assembly manual but I couldn't find anything re. the removal. I see a few small screws in the bottom of the cowling, but there has to be something else that is bigger and stronger. Any advice/direction would be welcomed. Thanks, Carmine.
