[Healeys] Electric water pumps

[Bob Spidell]

Same with my dad's old Model A I drove to high school and JC. When the 
wipers 'worked,' they didn't do shit anyways (but they worked better 
than the mechanical brakes). Funny, even some modern cars haven't solved 
the 'Wiper Mystery' completely (but I don't have any of the high-priced 
marques, maybe they work better and yes, I've tried the fancy bladed, 
silicone wipers and other blades).
