wiper motor

[chevyfiftynine]

Hi guys,

I have a '58 235 Apache and the wiper motor needs attention. It stopped in the middle of a downpour, but came back to life later. If I can remove it I'll see if the bushes just need replacing, rather than buying a new motor. It looks like the screws have special heads on the scuttle below the hood. I don't suppose I'd find the correct tool, but do they just unscrew with a large slotted screwdriver? Is this how to get access to the motor, or can it be done inside the cab? Anything else I might encounter?

Barry.
