Rack replacement went easy and fits perfect. Also, it's redesigned from the original and is much roomier. As far as the gasket goes, its WAY beefier than the original and the track on the top rack hits it when pulled out. The bottom racks wheels also hit the gasket pulling it out from the gasket seat. Because of this extra beef you really need to close the door with force. As far as the seal working, it didn't leak when I ran it.
