1950 Deluxe vacuum wiper motor rebuild kit

[ol-nobull]

Hi.   Have problems with wiper motor.   Have plenty of vacuum & new hoses and vacuum booster but poor wiper action.   My guy took the wiper motor out and says there is a hole in part that causes paddle to move and needs a rebuild kit.   I really need to get the car on the road and we are having nothing but rain with no relief in sight.    Does anyone have a source where I can purchase the rebuild kit?  If so please let me know either here or email    
I know I could drive with rain X but still want them fixed.     
Thanks, Jim
