I found the right angle hose on rockauto's site via a photo. Because I purchased half a dozen hoses at the same time (see my post over on the silhouette forum about hoses) I can't say what the part number was, but the photo was accurate.
The water outlet gasket sounds like it could be correct, but I didn't purchase that one--I had one that fit from a freon replacement seal kit. It has nothing to do with the thermostat however.
