I've done two ashtray repairs. #1 I re-made the little V-shaped catch on top of the ashtray drawer using THE MAGICAL HACK OF SUPER GLUE AND BAKING SODA!! It took a couple hours of build-up and grinding/smoothing with a Dremmel tool, but its operating just like new! The super glue/ baking soda thing is supposed to be stronger than plastic, so i hope it's permanent!
#2 i accidentally broke the change door OFF at the hinges. I super glued the hinges back in place and then built up around the hinges with super glue/baking soda. It looks pretty stout from the bottom and its a stealthy repair on top. (barely visible) I'll try to post pics.
