How do I remove the rear bumper of my Gen 2 Wagon? I've been struggling with the bolts all day and it wont come off. There are like 3 or 4 screws that I need like a 1 inch long screwdriver to get them off. My bumper somehow slid off the round pin that holds the side of the bumper to the frame. Nothin is broken though...it just like slid off. I tried to slide it back on, but it's not very bendable. Please give me some tips...or should I just take it to a body shop?
