I've seen a couple people post cavs with the celica spoiler on them and wondered how well the fitment was on the trunk lid... like if it has to be mounted more towards the edge of the trunk or more forwards.... also what are the dimensions of the holes/ posts so if i was to buy one, where i'd drill the holes... also since i'd be getting rid of the 3rd brake light i was also wondering if anyone has mounted the oldsmobile aurora 3rd brake light ( the one that is an LED strip that goes along the roofline in the rear glass..... thanks guys
