I haven't used the reproductions, but I do have a spare tail light panel for the right money, if you want to go that route. I know on the quarter extensions, the originals didn't fit very well. Mine were (in my opinion) pretty bad so I reshaped them so they fit nice and then found out they weren't supposed to fit nice. Oops! Unless I had a high dollar car, if I needed to replace the rear body parts, I'd go repop and just figure I'd have to work with them to make them fit. The advantage would be that if some dumb *** on their cell phone parks in your trunk, you didn't lose expensive original pieces. Just my .02
