Parts were ordered from www.1stsubaruparts.com which is Walker's Renton Subaru in Renton Washington (State) shipped promptly and received here in St. Louis in about a week. No sales tax of course but shipping was 10% of the order price. These folks are selling at 28% off list price. All of the Subaru dealers here in St. Louis sell at list price so there was a pretty good savings there.
You don't need to replace all these parts for a simple timing belt change but the car has 180,000 miles, this is the second timing belt change, it's my wife's car and I wanted to make it as reliable as possible, so I decided to replace everything on the list.
Hope this helps!
