Yup, should have. That one is rotted the worst on my Wag. I know BJ's has them. I have the tailgate set in my FSJ favorites list (on the internet explorer) Can't help ya with your other question... Im not sure how to get out or in. Im sure you could look it up, and probably find even videos of the process on youtube...most likely featuring other vehicles.
