Ok, hereby the pics of what I call the "Jilles mod".
It basically is a radiotray which has more material removed at the front and the second row of screws have been replaced by a countersunk screw with an O-ring.
You can see the 3 countersunk screws with the O-rings, basically you tighten them fully and then back them out around a half a turn. I used a little loctite the first time I fastened them.
The cutouts on the front of the radiotray have been widened about 3mm per side, check the gap between the middle axle mount and the radio tray.
