There is a thread on it. For some reason, I went over 3/4" and still couldn't get it to fold down. Conversely, you can cut down the nylon and metal hooks on the back of the seat to accomplish the fold down without raising. Or you could do a combination of both.

Edit: the above link starts in 2011. Their were changes for 2013+ trucks to the rear wall hooks and latches. Look for posts/threads for 2013 and later trucks...
