Has anyone put a 2013 gt500 rear diffuser on a 2010 gt500? If so what did you have to do? I thought I seen someone on here that has done that.
You would have to replace the rear bumper cover to a 2013-14 (any model, although the cutting will have to be done) for the diffuser to work.
+1. It's better to buy a '13-'14 bumper cover than to try to modify a '10 to accept a '13-'14 valance.The bumper cover and tail lights won't line up if you bought a 13 bumper cover. Like said above boss and GT/ CS cans be modified easily for MY 10-12. I'm not saying you can't but to modify a 10 cover to accept a 13 valance would take a lot of work. Google some pics.
