I have spent the last 2 weeks making the tool that is necessary  to remove the rear seats from the Gwagen and MLs. I needed one to remove my seats for space when traveling.
I will be glad to share the diagram with anyone that would like to have it. 
The tool is a pair of "Vise Grips" TM with 2 attachments. I will be glad to sell the 2 machined parts for anyone that has a shop and can weld the attachments to the Grips. Instructions included. 
The complete tools sell for $60 plus postal costs. I have not determined the cost of the additions at this time, but will do so soon and it will surely save you a lot. 
My email to anyone that wants a picture is below. Be sure to note on the subject line that it concerns the "Tool".
