Review on Metra 82 5604 Speaker Transit Vehicles by Todd Worley

The kit I received only had 4 pieces not 6 as shown in the picture. The bag that the parts came in says the instructions are on both the front and back. I went to the Metra website and couldn't find any instructions. I then emailed Metra Tech Support. No phone support as today is Thanksgiving weekend. I was told there were no instructions. It is completely unclear how these parts are to be used to attach the loudspeakers. I took the car apart, ready to install the speakers and was stuck.
