Looks pretty good... anyone want to buy it and give a report?

Many of the Japanese cars share a lot of the same "kinds" of parts. Looking at them in the JY would probably help you find something similar. In this case, probably any reservoir of the right shape would work, with mounting it to the Z car being the biggest problem.

I looked at that a few days ago too. For the $45.00 it will cost to get it, it would seem logical to stick with used OEM parts. Just my opinion. A few years ago the 'universal' replacements were in most of the stores like NAPA, Auto Zone, Pep Boys, etc. I have not looked lately, so they may still be available. Many of the used ones available that do not work can be made to do so by tapping on the motor a few times while it's powered up. Seems like they freeze up after a few years of inactivity. I've picked up at least two of them that were inop & they worked just fine after powering on/off several times & tapping them. Just a thought / suggestion if you've got a dead one looking at you.....

You probably need to decide if you just want a tank that holds water, and a pump to squirt it, or an authentic-looking thing. If you are lucky, you might find a tank that's the same with the integral washer pump, but a diffent cap. Swapping the caps should make it work.

thx

Mine developed a crack this winter while in storage due to the cold and age. I got a brand new identical factory Nissan washer reservoir for it. not cheap but I want to keep my beauty original I'll be putting it in soon when I get her back out for spring/summer. waiting for the roads to get cleaned up first.
