Send me your money, and I'll send you a set of "Custom built" just for you, wiper motors.
Motors is motors is motors.
Most of them have adjustments to limit the amount of swing and where they park.
If you really want some that are custom made, just for you, I'll be happy to send a standard wiper motor, (air or electric), out and have the engraved for you.
By the way, my prices aren't listed, because of the $50 limit. But if you want to send me 10 times that much, I won't holler!
