Hey Adam & Jeff,
OK...I've taken the butt part of the seat off. Then I've taken the 2 small retaining bolts and 2 large holding the seat belts and seat backs.
But now it seems to also have some sort of retainment in the upper part of the seat back. Is this in the trunk or elsewhere?
I'm going to crawl and investigate further, but can you guys give me a minor hint?
