Direct PARTS connection
The link will take you right to the part you need. In the Illustration it is labeled #4, but it's on $3.51 not sure about shipping.
I got hosed on Ebay for $12.00 after shipping.
It took 2 minutes to take the broken one off and place the new one in place. You need a hex head screw driver deal, it's not standard phillips or flat. You can also go to a U Pull It junkyard and gank one off a crashed 300 in the lot. not sure about price.
