1990 Chrysler New Yorker Speed Sensor

We aren't a parts supplier. Try the Rock Auto web site if you can't get the sensor from a local auto parts store. Also do a search for "Pull-A-Part" and see if there's a yard near you. Their yards are all very clean and well-organized, and parts are real inexpensive.

I may have a solution. I looked up the sensors for my car, a '93 Dynasty, which is the same body style. The same rear sensors are listed for a '90 New Yorker, a '90 Dynasty, and a '93 Dynasty. That suggests the computers in all of them require the same signals and the front sensors will likely be the same too. Look up your sensor for a '93 Dynasty and see if it looks like yours. It's the magnetic pickup and its mounting that need to be the same. If the connector is different you may be able to remove the terminals and put them in your old connector body.

Very often the only difference between sensors of different years is the clip-on plastic attachments that hold the cable to the body or strut, but that's enough to earn it a different part number. The parts suppliers don't make that judgement call when it comes to listing the parts though. If the part number is different than what's specified for a car model, they won't list it at all. Sometimes mechanics who go to work for an auto parts store will be able to tell you which parts will interchange and what's different about them. In this case you have the luxury of a picture to look at.
