Went on easy and fit great. Since all of the hardware was bright stainless steel - I sprayed a coat of black epoxy over the bolt heads to make them less noticeable.
These are very high quality mud flaps. However, because the Z brackets did not fit as described the first mud flap install on the drivers side took me 3 hours to install. Following the directions would just not result in a mud flap that was hanging level. My first career was an auto mechanic for twenty years so I must say I have some skills. After revising the installation sequence the second mudflap was installed in about an hour. Very heavy duty product that looks first class on my 2011 Mega Cab Dually!!
