I just put mine on today.......it was on of those "should take 15 minutes but too 3 hours" mods.......
When i was taking the door of the assembly the spring and rubber piece went flying. The spring was ok but the rubber piece flew into the sewer hole on my street!!! So i had to fabricate my own piece out of a rubber stool-leg cap!! hehehe.....my first "ghetto" mod!
BTW i don't know if anyone else did this but instead of using brackets I just drilled holes in the tabs and put the long screws through them! This way its not gonna be so easy to steal.....
