#1 - SO DAMN GLAD I found this thread!!!
I will be changing my oil in about 800 miles (after 9k miles, I run synthetic) and to be honest I'm not sure if mine has broken yet or not (I hope it's still in place).
#2 - watched the video about the proposed Dorman part and made note of the part number on the box...
Dorman has it listed on their web site and it should be available at your local NAPA/O'Reilly/whatever parts store.
However, you can also buy it from Amazon:
I'm going to buy one to be safe.
If mine hasn't broken yet, it probably will soon and with the kit sitting on the shelf (figuratively speaking) it will be an easy fix.
