I have a 1993 SDV, I am trying to take out the 6 x 9's in the back. Before you flame me, I have read every post on here, on how to do this. Here is my problem, I have taken off the top and back linings in the trunk and can find no super long stud people keep metioning, no blue bolts/studs and nothing a 10mm socket would fit too. There is nothing coming out of the back of the trunk from the rear seats. The only thing I can find is two small studs lateral to each speaker with a flat washer (about the size of a half dollar washer looking thing with three symetrical holes in it), that will not move regardless of the pressure put to them. Other than that, there is no stud or bolt to be found back there. Does anyone have a clue what these are for and what I am doing wrong, I would appericate it, thanks.
