They work great and aren't as expensive as many other replacement mounts. One of them held the barrel better than the two I had. I installed them on my 2011 Dodge Challenger and the trunk is VERY heavy. I usually open the trunk at least twice a day as I use the car for work. That's a lot and you won't regret it. VERY easy to install. PROS: Easy to install Looks like a factory original VERY strong CONS: No quantity (2) BOXI Rear Rack Brackets for Chrysler Challenger 2008-2016 Dodge Challenger 2008-2016 Coupe 2 Door Trunk with Spoiler 04589645AA 6657
