I want to install a three speed wiper setup in my 70 Cuda. I bought parts that I believed would fit but am having issues with the crank connecting to the linkage arm. Stud on crank is not long enough or bushing is incorrect.

There seems to be a lot of different numbers out there for what will work in the car. There used to be site "lighteningjar" that had a great search engine for confirming parts / interchangeability but that is no longer working. Is there anywhere else that I can match the numbers on my pieces to confirm whether they are correct or not.

The linkage arm is 3431 514 58622 and the crank is 2822 28 58622.

Thanks.
