If "no drilling" means "a lot of drilling" then of course it will fit perfectly. If you're advertising a product that fits all 09-13 Chevy 2500 models, I suggest making sure it actually fits. The bumper on the 2500HD is completely different and I had to drill a few holes to make this mount work. I was expecting screw caps at hard earned prices but instead I got fake Chinese quality. Next time I'll pay for fakes too. Lesson learned.
