Two speed Wiper motor

[jansV8]

I' m jans from the Netherlands and the owner of a Toronado from 1966 (base model).
My problem is to find a two speed wiper motor (without washer ass.), because the other one is out of order.
The original one is a wiper annexed washer but I have allready have a separate washer assembly build in.
Because there are only a few Toronado's in the Netherlands, spare parts are very difficult to find.
My question is which model two speed motor of GM or are usa cars can I build in my 1966 Toronado.
Thanks anyway.

I don't understand; you can continue to use the wiper motor even if the washer
pump is disconnected. I ran the washer wires over to a unit with the motor under
the tank, so it never loses its prime (and actually always works).

A higher goal is to convert to delayed wiper. Bruce Roe
