Well after 31 years my washer pump has failed. What options do I have for a replacement? Are they interchangeable with other years?

Thanks

Several options:

Buy a new one from Midwest Z, Chloe said she has them;

try your luck finding a used one (that works) on this sight or EBay;

Chloe mentioned to me that an early Honda pump of the same style clips on to the washer, for much less money. You will have to switch one of the wires, which is opposite than the Datsun one.

Good luck.
