I use http://www.rockauto.com/ quite regularly as well, it is a US market site. It has images to help, but you just need to double check they aren't a generic image.
There is the risk of parts not being compatible, but the prices are far cheaper for aftermarket parts. That being said I have only had 3 parts that were not correct, due to local manufacturing here in Australia being slightly different. 3 parts different out of hundreds isn't too bad.
The OEM part number you listed also matched with the US OEM parts manuals as well.
