Fire wall moving

I keep hearing say they had to move their firewall in early A bodies to make room for a 318. What did you do about the windsheild wiper motor?

I'm not sure what year early A you have, but the one in my profile picture is a 1966 with factory v8. no firewall isn't different or moved, it has wipers

who would want to remove the wipers? what happens if it rains?
