If you still have your original York compressor bracket (or can get one from a junkyard) you can use this bracket from NAP to mount up a new Sanden style compressor. Which is what I'm gonna do if/when my York goes out. I've heard York's don't last too long after switching to R134.

Here is a complete kit with nearly everything but the evaporator, and it does come with mounting bracket too.
