most original factory pumps I've seen have 3 holes. not sure about a 4-hole pump - aftermarket or repro? originally, the pump mounts with the 3 rubber plugs - no bracket. you have to push them into the holes. if the rubber is in good shape just lube them with liquid soap or petroleum jelly and they'll push in with some effort. if not use a blunt rod the diameter of the hole in the top of the rubber plug to insert them
