Theres a guy here that does nothing but old stuff. I mentioned the vacume wiper thing to him. He said what he and the guys did when he was young(a long long time ago) was put vasaline in the bowl of the wiper motor. I went through 5 motors looking for a good one for my 54 and found one. A good one can take your finger off. Don't put your finger in it to see how strong it is. I know somebody who did that.
