I am going to try to post a picture of my "quick disconnect link".
I make all the parts, except the bolts, washers and the quick release pin (that is the shinny piece in the center of the aluminum button).
The round aluminum button is attached to a quick release pin. When the pin is pulled the link screwed to the header can slide out of the quick disconnect link. This allows the header to be stowed with the bottom forward and will then clear high back seats.
Just thought you would like to know.
