If you can't find a replacement you might be able to have it rebuilt. There is a company Cardone that does this but you have to go through a retail store such as Autozone. Their website has a search feature that lets you see if they have a replacement or if it can be rebuilt
Be careful with trying to use a non matching number. While the numbers (and the actual motor) may be close, the wiring and connecters can be very different.
