The unit pictured attached is what I wanted with four mounting holes in the heatsink. From what I got, only the heatsink seems to be slightly smaller and there are no mounting holes in the heatsink. The product is probably ok, but without installing it I can't say. It might be possible to get it working with some tweaking, but I don't reward vendors who don't update their listings. Came back and ordered the Trane version, hopefully it is as pictured and fits without too much hassle.
