Install went fine. Used the diagram supplied and the install Videos. The no-drill assy is sturdy, rigid, and secure compared to several other's I've had/tried in my past. Went onto the TREMOR F350 w/o any issues. The Carb-grey with the gunmetal flaps looks really amazing. I'll bump to 5 once I run them over winter in rural MI and dirt, snow and slush for 6 Mos. :-)
Pretty easy instructions, use an Exacto Knife to cut out slots on template. Use a Silver Sharpie to transfer hole pattern. Drill both ends of slot with drill bit, & use utility knife to cut the long slots. Only issue was Top Slots on Driver side Template ( see photo), did NOT align/ off by about 3/8”. Had to cut a much larger hole. All the other screws aligned perfectly. Start the Existing Factory screws loosely to start until the are all in.
At first I considered not purchasing these brackets but after completing the installation, the quality and fit convinced me these are worth the price. One word of caution, I discovered the templates are different when printed on my laser printer compared to those sent with the brackets.
