Just a heads up man, I used u-bolts and fender washers to secure the Drifters to the brackets. Don't depend on the throw-over strap. If you do, the strap will rip out the plastic backs real quick. When I contacted Saddlemen after the first set backs cracked it was their recommendation that the bags be secured with additional hardware. I was concerned about the warranty and was advised it was OK. The more you can spread the weight through the backs to the bars the longer they will last. Especially if you load them down like I do.
